I gave a bottle of MedTerra to my daughter for anxiety and 2 hrs. I have read lots of articles about CBD and no one ever mentioned a side effect like that.
Medterra has removed my review 2x. Ill shorten my very lengthy review that I left on their page. It also made me tired. Whiskey does the same thing though for a fraction of the price. It gave me bad headaches as well. So I question if I am actually allergic to it. I did take the entire bottle and even upped my dose. It also went rancid. I question if oxygen exposure causes that.
It was stored properly. Imo- It is snake oil. The placebo effect is strong with this one. I now have to cancel my checking account and get a new account,and this is going to cause me all sorts of headaches. After researching products for a few weeks I purchased the mg 30ml bottle from them.
After just the first dose…1ml in the evening I had one of the best night sleeps in about 6 months , which due to extreme pain from a variety of issues…ie…Fibromyalgia, RA, OA, Shoulder Bursitis and I am in need of a right hip replacement my sleep has been anything but restful.
I know it will take some tweaking to get the right dosage to accommodate my issues but I am a firm believer that this product will work! Thank you Medterra for your high quality product and Thank you MarijuanaBreak for your great reviews!
Best CBD I have tried, hands down!! I take 50mg per day for my arthritis. Great review by the way marijuanabreak! To be honest I had been on mg bottles and I had multiple symptoms go away felt great.
I was sure there was no CBD oil in it. Rate and write a review Cancel reply. So how to choose the best? The quality of the CBD oil itself is obviously the most important factor — and many companies do take the quality of their products seriously. To reward those companies, we gave more weight to the quality of the product than any other category.
With so many companies to choose from, though, we had to further refine our list. So we looked at other factors to determine which companies are the best and the most trustworthy. So we scrutinized the transparency of the manufacturer, the customer experience, and the value for your dollar.
Where the hemp was grown To determine the quality of the CBD oil, we started with the source — where the hemp was grown and whether it was grown organically. Domestic sources allow for more oversight over farming practices, so companies that source their hemp in the U. Companies that source from farms that utilize organic practices got higher marks. Broad spectrum CBD oil includes a range of other cannabinoids, but minus the THC — which is generally what people using isolates are trying to avoid.
We gave the highest points to companies that use a CBD distillate for their tinctures. The process of distillation creates an extract that is pure on a molecular level. There are people who think distillate is too pure, and that a full spectrum decarb produces a more effective tincture.
But in light of the inconclusive evidence, we prefer a distillate. The process allows for a high degree of control as to the finished product.
Flavor Which segues neatly into our final quality marker — namely, taste. True, taste is subjective. But there are companies putting a lot of resources into making their tinctures palatable. And then there are tinctures that just taste plain bad. For this category, we put a lot of weight on how they deal with third-party lab testing.
First, we rated them on how easy it is to find those lab test results — as well as how much they tested for. All lab tests should test cannabinoid levels, but we really appreciate companies that also let us see testing results for contaminants like pesticides, heavy metals, and residual solvents. We then asked how often they have third-party testing performed top marks for those who send every batch to a third-party lab.
And we gave points to companies who make it really easy to find information on extraction and sourcing. So we posed as customers and went through the whole shopping experience. This included everything from navigating the website and sending out customer service emails to going through the checkout process — as well as noting shipping and returns policies. We also gave a few points based on the design and appearance of both their website and bottle.
The score, out of , breaks down to 70 percent for price and 30 percent for quality. This brings some balance to the list since, for most of us, cost definitely matters. They are all selling high-quality products, with third-party lab tests to back them up. We went with the best evidence available for example, in privileging full-spectrum oils over isolates. But otherwise — where evidence is inconclusive, we made decisions based on our own experience and preference. And there are some new additions!
In short, Cannabidiol — or CBD — is a cannabis compound that has many therapeutic benefits. Usually extracted from the leaves and flowers of hemp plants — though marijuana can also be a source — CBD oil is then incorporated into an array of marketable products. These products vary from the most common, like sublingual oils and topical lotions, to the less common think CBD lattes. Basically, if you can dream it, you can buy it.
How does CBD Work? The endocannabinoid system is spread throughout your brain and body, but primarily throughout your central nervous system. The interaction between cannabinoids and receptors is what produces effects like the regulation of mood, pain, appetite, inflammation, and memory. Plant-based cannabinoids, found in cannabis plants, also interact with the receptors whimsically named CB1 and CB2 in the endocannabinoid system, and each affects your body in different ways.
But CBD is a special snowflake among cannabinoids. This unique interaction creates systemic, whole-body benefits that include, but are by no means limited to: CBD is a non-psychoactive component of the cannabis plant.
So, no, it will not make you high. There are at least different cannabinoids that can be isolated from cannabis plants, each of which has its own effects. THC or tetrahydrocannabinol is the only cannabinoid responsible for the high that people get from marijuana. This property makes CBD highly useful as a medical treatment for a wide range of conditions. Each cannabinoid has its own properties and confers its own benefits.
Working together, a synergy is created that boosts the healing properties of CBD. The government regulates concentration levels of THC at 0. But THC metabolites are stored in the fat cells of your body, building up over time. If you ever need to take a drug test, this could create an issue for you. CBD Isolate is just that — CBD that has been isolated and then refined to remove all other terpenes, cannabinoids, and plant material. This process eliminates the trace amounts of THC that would otherwise be present.
The result is a fine white powder containing only the pure CBD chemical compound. This isolate is then combined with carrier oils like hemp seed oil or MCT oil to create marketable products. While those in the These terpenes may enhance the effectiveness of CBD — or maybe they just make it smell good. This may be a good place to point out that not all CBD products are created equal.
The industry is still largely unregulated, and the quality and quantity of CBD in a given product will vary wildly. Another point worth clarifying is the difference between hemp seed oil or hemp oil and CBD oil. However, hemp seed oil does not contain any concentration of cannabinoids at all, including CBD. So by all means, stock up at your local natural food store. And now, onto the thorny issue of legality. The simple answer to the question is yes — if it is extracted from hemp.
The Farm Bill established guidelines for growing hemp in the U. CBD derived from marijuana is a different story, and the law varies from state to state. And what research supports these claims? The science behind CBD is in the relatively early stages. As a cannabinoid, we know that CBD interacts with receptors in your endocannabinoid system. The endocannabinoid system is integrated throughout your body — and this widespread, whole-body interaction creates a broad range of effects.
Hence, the long list of possible benefits. But those who deal with chronic pain know the debilitating, life-sucking reality of this condition. And traditional medications often come with long lists of side effects which can be as debilitating as the pain itself. So when word started getting out that CBD has the potential to reduce pain without those side effects, it seemed too good to be true. In fact, numerous studies have looked at the relationship between CBD and pain, and the results are promising.
Researchers have looked at various kinds of pain — from joint pain to cancer pain. One finding is that CBD increases levels of glutamate and serotonin — both neurotransmitters that play a role in pain regulation. Both conditions have been treated with a variety of medications, courtesy of Big Pharma, that have had varying levels of success.
Again, the long list of side effects can be off-putting to someone who just wants to get through the day without the sweaty tension of anxiety or the gray haze of depression. Another study showed CBD to have antidepressant effects comparable to those of the prescription antidepressant Imipramine. These studies point to the need for more research to be done on CBD. But for those who have had limited success with prescribed medications, talking with your doctor about using CBD as an alternative is worth consideration.
CBD and Insomnia Sleep, the sweet elixir of the gods. So natural, but for many of us, so sadly elusive. We exercise, we avoid things that we really, really want — like naps and caffeine. And still, the magic escapes us. But help is near. CBD, with its calming, anti-anxiety effects, is helping many people get the sleep they need — without the groggy side effects of many sleeping pills. There are lots of things that can keep a person awake — from anxiety or depression to chronic pain. CBD and Seizures In the United States, over three million people suffer from epilepsy — , of those people are children.
Epilepsy is a disorder of the brain that causes seizures — of which there are over thirty different kinds, ranging from mild and infrequent to life-threatening. Not surprisingly, people with epilepsy face significant challenges — from the cost of healthcare to work limitations and social isolation. All samples with added hemp flour had much better nutritional qualities than the brown rice flour crackers in terms of higher protein, crude fibers, minerals, and essential fatty acids content.
Likewise, all samples with added decaffeinated green tea leaves had much better antioxidant properties than crackers with no added green tea leaves. All samples had antioxidant properties, even without the addition of green tea leaves. Optimization of the responses was conducted based on the maximized values for protein, fibers, omega-3 fatty acids content, as well as for the antioxidant activity and overall score.
This formulation has demonstrated potential application in the baking industry and marketing of these gluten-free crackers as a value-added functional product. Hemp seed oil press-cake as a by-product of cold-pressed oil processing and brown rice flour were used to design a functional gluten-free snack-type product-savory crackers.
Green tea leaves were added to improve antioxidant activity, which greatly. Immunomodulatory and therapeutic effects of Hot-nature diet and co-supplemented hemp seed , evening primrose oils intervention in multiple sclerosis patients. Multiple sclerosis MS is the most chronic and inflammatory disorder. Because of limited efficacy and adverse side effects, identifying novel therapeutic and protective agents is important. This study was aimed to assess the potential therapeutic effects of hemp seed and evening primrose oils as well as Hot-nature dietary intervention on RRMS patients.
In this double blind, randomized trial, MS patients with EDSS hemp seed and evening primrose oils with advised Hot-nature diet, "Group B" who received olive oil , "Group C" who received the co-supplemented oils. There was no significant difference in studies parameters at baseline. After 6 months, significant improvements in Mizadj, EDSS and relapse rate were found in the groups A and C, while the group B showed a border significant decrease in relapse rate. Immunological parameters showed improvement in groups A and C, whereas there was worsening condition for group B after the intervention.
The co-supplemented hemp seed and evening primrose oils with Hot-nature diet have beneficial effects in improving of clinical score in RRMS patients which were confirmed by immunological findings. Published by Elsevier Ltd.. Erythrocyte membrane fatty acids in multiple sclerosis patients and hot-nature dietary intervention with co-supplemented hemp-seed and evening-primrose oils.
The risk of developing multiple sclerosis MS is associated with increased dietary intake of saturated fatty acids. For many years it has been suspected that this disease might be associated with an imbalance between unsaturated and saturated fatty acids. We determined erythrocyte membrane fatty acids levels in Hot nature dietary intervention with co-supplemented hemp seed and evening primrose oils in multiple sclerosis patients.
To determine the erythrocyte membrane fatty acids levels and correlate it with expanded disability status scale EDSS at baseline after 6 months intervention in MS patients by gas chromatography, in this double blind, randomized trial, RRMS patients with EDSS hemp seed and evening primrose oils with advised Hot nature diet. There was no significant difference in the study parameters at baseline.
After 6 months, EDSS, Immunological parameters and the erythrocyte cell membrane with regard to specific fatty acids showed improvement in the group A and C, whereas there was worsening condition for the group B after the intervention.
We concluded that Hot-nature dietary intervention with co-supplemented hemp seed and evening primrose oils caused an increase PUFAs in MS patients and improvement in the erythrocyte membrane fatty acids composition. This could be an indication of restored plasma stores, and a reflection of disease severity reduction.
Effect-directed analysis of cold-pressed hemp , flax and canola seed oils by planar chromatography linked with bio assays and mass spectrometry. Cold-pressed hemp , flax and canola seed oils are healthy oils for human consumption as these are rich in polyunsaturated fatty acids and bioactive phytochemicals.
However, bioactive information on the food intake side is mainly focused on target analysis. For more comprehensive information with regard to effects, single bioactive compounds present in the seed oil extracts were detected by effect-directed assays, like bioassays or an enzymatic assay, directly linked with chromatography and further characterized by mass spectrometry. This effect-directed analysis is a streamlined method for the analysis of bioactive compounds in the seed oil extracts.
All effective compounds with regard to the five assays or bioassays applied were detected in the samples, meaning also bioactive breakdown products caused during oil processing, residues or contaminants, aside the naturally present bioactive phytochemicals. The investigated cold-pressed oils contained compounds that exert antioxidative, antimicrobial, acetylcholinesterase inhibitory and estrogenic activities. This effect-directed analysis can be recommended for bioactivity profiling of food to obtain profound effect-directed information on the food intake side.
Careful consideration of the extraction method is very important for the measurement of cannabinoids in hemp seeds. Yang, Yi; Lewis, Melissa M. Vitamin purification and analysis in waste fish oil are reported for the first time here. Due to the short time and effectiveness of the proposed method, it can be easily applied in industrial processes. Stability of cosmetic emulsion containing different amount of hemp oil.
The aim of the study was to determine the optimal conditions, that is the content of hemp oil and time of homogenization to obtain stable dispersion systems. For this purpose, six emulsions were prepared, their stability was examined empirically and the most correctly formulated emulsion composition was determined using a computer simulation.
Variable parameters oil content and homogenization time were indicated by the optimization software based on Kleeman's method. Physical properties of the synthesized emulsions were studied by numerous techniques involving particle size analysis, optical microscopy, Turbiscan test and viscosity of emulsions.
Empirically determined parameters proved to be consistent with the results obtained using the computer software. The computer software based on Kleeman's method proved to be useful for quick optimization of the composition and production parameters of stable emulsion systems. Moreover, obtaining an emulsion system with proper stability justifies further research extended with sensory analysis, which will allow the application of such systems containing hemp oil , beneficial for skin in the cosmetic industry.
Hemp as an Agricultural Commodity. Oil from the crushed hemp seed is an ingredient in a. Characterization of Lignanamides from Hemp Cannabis sativa L. Hemp seed is known for its content of fatty acids, proteins, and fiber, which contribute to its nutritional value. Here we studied the secondary metabolites of hemp seed aiming at identifying bioactive compounds that could contribute to its health benefits.
This investigation led to the isolation of 4 new lignanamides, cannabisin M 2 , cannabisin N 5 , cannabisin O 8 , and 3,3'-demethyl-heliotropamide 10 , together with 10 known lignanamides, among which 4 was identified for the first time from hemp seed. Lignanamides 2, 7, and showed good antioxidant activity, among which 7, 10, and 13 also inhibited acetylcholinesterase in vitro. The newly identified compounds in this study add to the diversity of hemp seed composition, and the bioassays implied that hemp seed , with lignanamides as nutrients, may be a good source of bioactive and protective compounds.
They were prepared by solid-phase synthesis, and tested for ACE-inhibitory activity. Planting date and seeding rate effects on sunn hemp biomass and nitrogen production for a winter cover crop.

In conclusion our results show that C. Published by Elsevier Ltd. Elevated nitrogen N fertilizer costs have renewed interest in alternative N sources, such as legumes. A randomized complete block design with a split-plot restriction and fou Cannabidiol CBD -based treatments for several diseases, including Tourette's syndrome, multiple sclerosis, epilepsy, movement disorders and glaucoma, are proving to be beneficial and the scientific clinical background of the drug is continuously evolving.
Patients' quality of life was evaluated using the medical outcome short-form health survey questionnaire SF Two patients dropped out due to iatrogenic adverse events and another two patients stopped the treatment early due to lack of any improvement. SF showed significant benefits in the physical component score P hemp oil also significantly reduced body pain according to the SF assessment. This study demonstrated the safety and tolerability of CBD-rich hemp oil and the primary efficacy endpoint.
Randomized controlled trials are warranted to characterize the safety profile and efficacy of this compound. Hemp is suitable as a renewable energy resource. The aim of this study was to clarify local hemp 's Cannabis sativa L. Arsenic As , cadmium Cd , lead Pb and titanium Ti presence in hemp was determined using an inductively coupled plasma optical emission spectrometer Optima DV. Arsenic content was higher in the shives than in the stems with fibre.
The ash content depends on non-organic substances which the plants absorb during the vegetation season. The lignin content depends on several factors: The unexplored factors have a great effect on the ash and lignin content. Hemp is suitable for cultivation and for bio-energy production in the agro-climatic conditions in Latvia. Boosting accumulation of neutral lipids in Rhodosporidium kratochvilovae HIMPA1 grown on hemp Cannabis sativa Linn seed aqueous extract as feedstock for biodiesel production.
The yeast showed boosted triglyceride TAG accumulation in the lipid droplets LDs which were transesterified to biodiesel. The sonicated HSAE prepared lacked toxic inhibitors and showed enhanced total lipid content and lipid yield Cannabis plants show a high Delta9-tetrahydrocannabinol content and are used as a psychoactive drug.
Therefore the cultivation of hemp and its possession are prohibited by law in Japan. Meanwhile, Cannabis seeds have been used as a component of shichimi-togarashi a Japanese spice , bird feed, or a crude drug mashinin. To exclude the possibility of germination, it is officially noticed that hemp seeds must be killed. However, the number of violators has increased in recent years. To judge the ability of seed germination, a germination test is performed.
However, the test requires several days and thus has not been used for on-site inspection. In this study, we developed a rapid detection method to determine the ability of Cannabis seeds to germinate using 2,3,5-triphenyl-2H-tetrazolium chloride TTC. The principle of the assay is as follows. The endogenous respiratory enzymes in hemp seeds convert added colorless TTC into red 1,3,5-triphenylformazan.
Consequently, a living embryo is stained red, while red does not appear in the dead seeds. The reaction was active over a pH range of 8.
Under the optimum conditions, we were able to determine the ability of seeds to germinate based on the presence of color within 20 min.
Since this method is rapid and simple, it is applicable to on-site inspections. In addition, it could be used as an alternative technique to the germination test, because erroneous decisions is cannot occur under the assay principle. Development of a hull-less pumpkin Cucurbita pepo L. Response surface methodology RSM was applied to investigate the effects of two factors, as the formulation's compositional variables: The selected responses were significantly affected by both variables P oil separation after 1 mo of storage.
An optimum spread was produced using 1. A use of by-products generated from different food processing technologies, where the edible waste is successfully incorporated as a value-added ingredient, has become a very important area of research to support global sustainability efforts. This study contributes to the knowledge of a product design process for oil -based spread development, where oil press-cake, a by-product of the oil pressing process of the naked pumpkin seeds , was used and where results have demonstrated that a new product can be successfully developed and potentially manufactured as a functional food.
Extraction and Analysis of Tomato Seed Oil. Tomato seeds represent a very large waste by-product from the processing of tomatoes into products such as tomato juice, sauce and paste. One potential use for these seeds is as a source of vegetable oil.
This research investigated the oil content of tomato seeds using several extraction technique Adaptive evolution of seed oil content in angiosperms: Studies of the biogeographic distribution of seed oil content in plants are fundamental to understanding the mechanisms of adaptive evolution in plants as seed oil is the primary energy source needed for germination and establishment of plants.
However, seed oil content as an adaptive trait in plants is poorly understood. Here, we examine the adaptive nature of seed oil content in angiosperm families occurring in different biomes across the world. We also explore the role of multiple seed traits like seed oil content and composition in plant adaptation in a phylogenetic and nonphylogenetic context.
It was observed that the seed oil content in tropical plants A significant relationship between oil content and latitude was observed in three families Papaveraceae, Sapindaceae and Sapotaceae indicating that selective forces correlated with latitude influence seed oil content. Evaluation of the response of seed oil content and composition to latitude and the correlation between seed oil content and composition showed that multiple seed traits, seed oil content and composition contribute towards plant adaptation.
Investigation of the presence or absence of phylogenetic signals across angiosperm families in 62 clades revealed that members of seven clades evolved to have high or low seed oil content independently as they did not share a common evolutionary path. The study provides us an insight into the biogeographical distribution and the adaptive role of seed oil content in plants.
The study indicates that multiple seed traits like seed oil content and the fatty acid composition of the seed oils determine the fitness of the plants and validate the adaptive hypothesis that seed oil quantity and quality are crucial to plant adaptation. A field study was conducted in and in Citra, Florida to evaluate the effects of seeding rate and removal of apical dominance of sunn hemp Crotalaria juncea L.
Three seeding rates of sunn hemp were used; a representative seed producti Elastohydrodynamic EHD traction properties of seed oils. The elastohydrodynamic traction coefficient tc properties of nine seed oils of varying chemical structures, PAO and hexadecane, were investigated using a ball-on disk traction apparatus.
The seed oils were: Elastohydrodynamic Traction Properties of Seed Oils. Effect of dietary supplementation of hemp seed Cannabis sativa L. This study was conducted in two separate experiments. Experiment I was conducted to investigate the effects of hemp seed HS on meat quality traits, and experiment II was designed to determine egg fatty acid FA composition in Japanese quail Coturnix coturnix japonica. In experiment I and experiment II treatments, groups were as follows: Raman spectra of pure Hemp essential oil and its different fractions show characteristic key bands of main volatile terpenes and terpenoids, which significantly differentiate them from each other.
These bands provide information about the chemical composition of sample under investigation and hence can be used as Raman spectral markers for the qualitative monitoring of the pure EO and different fractions containing different active compounds.
PCA differentiates the Raman spectral data into different clusters and loadings of the PCA further confirm the biological origin of the different fractions of the essential oil.
Challenges towards Revitalizing Hemp: Hemp has been an important crop throughout human history for food, fiber, and medicine. Despite significant progress made by the international research community, the basic biology of hemp plants remains insufficiently understood. Clear objectives are needed to guide future research. As a semi-domesticated plant, hemp has many desirable traits that require improvement, including eliminating seed shattering, enhancing the quantity and quality of stem fiber, and increasing the accumulation of phytocannabinoids.
Methods to manipulate the sex of hemp plants will also be important for optimizing yields of seed , fiber, and cannabinoids. Currently, research into trait improvement is hindered by the lack of molecular techniques adapted to hemp. Here we review how addressing these limitations will help advance our knowledge of plant biology and enable us to fully domesticate and maximize the agronomic potential of this promising crop.
Effect of unconventional oilseeds safflower, poppy, hemp , camelina on in vitro ruminal methane production and fermentation. Dietary supplementation with oilseeds can reduce methane emission in ruminants, but only a few common seeds have been tested so far.
This study tested safflower Carthamus tinctorius , poppy Papaver somniferum , hemp Cannabis sativa , and camelina Camelina sativa seeds in vitro using coconut Cocos nucifera oil and linseed Linum usitatissimum as positive controls.
The level of methanogenesis and the ratios of either the n Unconventional oilseeds widen the spectrum of oilseeds that can be used in dietary methane mitigation. In vivo confirmation of their methane mitigating effect is still needed, and their effects on animal performance still must be determined. Biocompatible nanoemulsions based on hemp oil and less surfactants for oral delivery of baicalein with enhanced bioavailability.

Published by Elsevier B. Fatty acid profile of kenaf seed oil. The fatty acid profile of kenaf Hibiscus cannabinus L. These reports vary considerably regarding the presence and amounts of specific fatty acids, notably epoxyoleic acid but also cyclic cyclopropene and cyclopropane fa Extension of oil biosynthesis during the mid-phase of seed development enhances oil content in Arabidopsis seeds.
Regulation of oil biosynthesis in plant seeds has been extensively studied, and biotechnological approaches have been designed to increase seed oil content. Oil and protein synthesis is negatively correlated in seeds , but the mechanisms controlling interactions between these two pathways are unknown. Here, we identify the molecular mechanism controlling oil and protein content in seeds.
Oil and protein biosynthesis in wild-type plants was sequentially activated during early and late seed development, respectively. The negative correlation between oil and protein contents in seeds arises from competition between the pathways. Extension of WRI1 expression during mid-phase of seed development significantly enhanced seed oil content. These results provide novel insights into potential breeding strategies to generate crops with high oil contents in seeds.
The aim of this study was to characterize the polyphenolic compounds and antioxidant activity of cold-pressed seed oil from Finola cultivar of industrial hemp Cannabis sativa L. Reactivity towards 2,2'-azino-bis 3-ethylbenzothiazolinesulfonic acid radical cation and ferric-reducing antioxidant power values were FHSO contains a significant amount of phenolic compounds of which The whole oil showed higher antioxidant activity compared with LF and HF.
Our findings indicate that the significant antioxidant properties shown from Finola seed oil might generally depend on the phenolic compounds, especially flavonoids, such as flavanones, flavonols, flavanols and isoflavones. Evaluation of chosen fruit seeds oils as potential biofuel. Oils available in mango, tangerine and African star seeds were extracted and characterized to determine their fuel worthiness for biofuel production.
Furthermore, the fuel properties of the three oils were within the range observed for some common oil seeds like rapeseed, soybean and sunflower, which are widely sourced for the production of biodiesel on an industrial scale. The low iodine values of the oil extend their applications as non-drying oil for lubrication purposes, however, the fuel properties exhibited by the oils enlist them as potential oil seeds for the production of biofuel and further research on the improvement of their properties will make them suitable biofuel of high economic values.
Para rubber seed oil: Para rubber seed was macerated in petroleum ether and n-hexane, individually, for 30 min. The extraction was additionally performed by reflux and soxhlet for 6 h with the same solvent and proportion. Soxhlet extraction by petroleum ether afforded the greatest extractive yield Although antioxidant activity by means of 1, 1-diphenylpicrylhydrazyl DPPH assay was insignificantly differed in soxhleted 8.
This extract was non cytotoxic towards normal human fibroblast cells. In addition, oleic acid and palmitic acid were determined at a greater content than in the seed of para rubber cultivated in Malaysia, although linoleic and stearic acid contents were not differed. This bright yellow extract was further evaluated on other physicochemical characters. The determined specific gravity, refractive index, iodine value, peroxide value and saponification value were in the range of commercialized vegetable oils used as cosmetic raw material.
Therefore, Para rubber seed oil is highlighted as the promising ecological ingredient appraisal for cosmetics. Transforming of the seed that is by-product of the important industrial crop of Thailand into cosmetics is encouraged accordingly. In many higher plants, seed oil accumulation is precisely controlled by intricate multilevel regulatory networks, among which transcriptional regulation mainly influences oil biosynthesis. Oil and major fatty acid biosynthesis in seeds was significantly promoted by myb mutation and MYB89 knockdown; thus, MYB89 was an important repressor during seed oil accumulation.
RNA sequencing revealed remarkable up-regulation of numerous genes involved in seed oil accumulation in myb89 seeds at 12 d after pollination. Posttranslational activation of a MYBglucocorticoid receptor fusion protein and chromatin immunoprecipitation assays demonstrated that MYB89 inhibited seed oil accumulation by directly repressing WRI1 and five key genes and by indirectly suppressing L1L and 11 key genes involved in oil biosynthesis during seed maturation.
These results help us to understand the novel function of MYB89 and provide new insights into the regulatory network of transcriptional factors controlling seed oil accumulation in Arabidopsis.
Biodiesel production methods of rubber seed oil: The utilization of rubber seed as raw material of biodiesel production is seen highly potential in Indonesia. The availability of rubber seeds in Indonesia is estimated about 5 million tons per annum, which can yield rubber seed oil about 2 million tons per year. Due to the demand of edible oils as a food source is tremendous and the edible oil feedstock costs are far expensive to be used as fuel, production of biodiesel from non-edible oils such as rubber seed is an effective way to overcome all the associated problems with edible oils.
Various methods for producing biodiesel from rubber seed oil have been reported. This paper introduces an optimum condition of biodiesel production methods from rubber seed oil. This article was written to be a reference in the selection of methods and the further development of biodiesel production from rubber seed oil.
Biodiesel production methods for rubber seed oils has been developed by means of homogeneous catalysts, heterogeneous catalysts, supercritical method, ultrasound, in-situ and enzymatic processes. Production of biodiesel from rubber seed oil using clinker loaded sodium methoxide as catalyst is very interesting to be studied and developed further. Synthesis biolubricant from rubber seed oil.
The polymerization reaction parameters investigated were reaction time, temperature and weight ratio catalyst with feed , and their effect on the bio lubricant formation. Viscosity of Common Seed and Vegetable Oils. Viscosity experiments using Ostwald-type gravity flow viscometers are not new to the physical chemistry laboratory.
Several physical chemistry laboratory texts 1 - 3 contain at least one experiment studying polymer solutions or other well-defined systems. Several recently published articles 4 - 8 indicated the continued interest in using viscosity measurements in the teaching lab to illustrate molecular interpretation of bulk phenomena.
Most of these discussions and teaching experiments are designed around an extensive theory of viscous flow and models of molecular shape that allow a full data interpretation to be attempted. This approach to viscosity experiments may not be appropriate for all teaching situations e. A viscosity experiment is presented here that is designed around common seed and vegetable oils.
With the importance of viscosity to foodstuffs 9 and the importance of fatty acids to nutrition 10 , an experiment using these common, recognizable oils has broad appeal. Background Rapeseed Brassica napus L.
The studies on seed structure and characteristics of different oil content rapeseed could help us to understand the biological mechanism of lipid accumulation, and be helpful for rapeseed breeding. The results indicated that the cytoplasms of cotyledon, radicle, and aleuronic cells were completely filled with oil and protein bodies, and YN had a high oil body organelle to cell area ratio for all cell types.
The high oil body organelle to cotyledon cell area ratio and the cotyledon ratio in seed were the main reasons for the ultrahigh oil content of YN The correlation analysis indicated that oil content is significantly negatively correlated with protein content, but is not correlated with fatty acid composition. The oil body organelle to seed ratio significantly highly positively correlates with oil content, and could be used to predict seed oil content.
Our results will help us to screen and identify high oil content lines in rapeseed breeding. The aim of the study is individual qualitively and quantitatively identification of fatty acids in Pkatsiteli grape seed oil , Phellodendron lavallei oil and Amaranthus seed oil and prediction of its biological activity.
Using high-effective liquid chromatogramphy fatty acids were franctionated. Their relative concentrations are expressed as percentages of the total fatty acid component. Identification of the fatty acids consituents is based on comparison of their retention time with that of known standards. The predominant fatty acids in the oils were palmitic, oleic and stearic acids.
The investigation demonstrated that fatty acids composition takes marked part in lipid metabolism of biological necessary components. The most interesting result of the investigation was the detection of unusual for the essentain oil begenic acid. Seed oil is important not only for human and animal nutrition, but also for various industrial applications. Numerous genetic engineering strategies have been attempted to increase the oil content per seed , but few of these strategies have involved manipulating the transporters.
Pyruvate is a major source of carbon for de novo fatty acid biosynthesis in plastids, and the embryo's demand for pyruvate is reported to increase during active oil accumulation. In this study, we tested our hypothesis that oil biosynthesis could be boosted by increasing pyruvate flux into plastids. The total seed number did not differ significantly between the WT and OEs. Taken together, our results demonstrate that seed -specific overexpression of the pyruvate transporter BASS2 promotes oil production in Arabidopsis seeds.
Thus, manipulating the level of specific transporters is a feasible approach for increasing the seed oil content. Optimization of mechanical extraction conditions for producing grape seed oil. The health promoting properties of grape seed oil is due to the presence of many bioactive components Thermal and storage characteristics of tomato seed oil.
Thermal oxidative stability and effect of different storage conditions on quality characteristics of tomato seed oil have not been studied. The objectives of this research were to determine the changes in quality and oxidative stability of tomato seed oil , including color, antioxidant activity, per Fatty acid profiles of some Fabaceae seed oils.
The fatty acid profiles of six seed oils of the Fabaceae Leguminosae family are reported and discussed. These are the seed oils of Centrosema pubescens, Clitoria ternatea, Crotalaria mucronata, Macroptilium lathyroides, Pachyrhizus erosus, and Senna alata. The most common fatty acid in the fatty a Continuous hydrolysis of Cuphea seed oil in subcritical water.
Cuphea seed oil CSO is a source of medium chain fatty acids for use in chemical manufacturing, including detergents, shampoos and lubricants. Cuphea seed oil is high in decanoic acid and this fatty acid is especially useful in the preparation of estolide biobased lubricants, which have excellent Soybean is the most important oil crop in the United States.
Production of soybean seed oil requires coordinated expression of many biological components and pathways, which is further regulated by seed development and phyto-hormones. A new research project is initiated in my laboratory to delineat Seed oil and fatty acid composition in Capsicum spp. The oil content and fatty acid composition of seed of genebank accessions total of nine Capsicum species, and a single accession of Tubocapsicum anomalum, were determined.
The physicochemical characteristics of oil extracted from seed of C. Supercritical carbon dioxide extraction of cuphea seed oil. Cuphea seed oil is being investigated as a potential domestic source of medium chain fatty acids for several industrial uses.
Although the oil from cuphea seeds has been obtained using both solvent extraction and screw pressing, both methods suffer from several disadvantages. Integrated utilization of red radish seeds for the efficient production of seed oil and sulforaphene. Supercritical CO2 was used to obtain seed oil from red radish seeds. The influence of pressure, temperature, CO2 flow rate and time on extraction yield of oil were investigated in detail.
The maximum extraction yield of oil was The physicochemical properties and fatty acid composition of oil indicated that the seed oil can be used as a dietary oil. Meanwhile, the high purity sulforaphene The initial pH, R, extraction temperature and extraction time for each cycle had a considerable influence both on the extraction yield and purity of sulforaphene of crude product.
The extraction of oil was directly responsible for an increase of The oil palm seed production unit that generates germinated oil palm seeds is the first link in the palm oil supply chain, followed by the nursery to produce seedling, the plantation to produce fresh fruit bunches FFB , the mill to produce crude palm oil CPO and palm kernel, the kernel crushers to produce crude palm kernel oil CPKO , the refinery to produce refined palm oil RPO and finally the palm biodiesel plant to produce palm biodiesel.
This software contains European and US databases on a number of materials in addition to a variety of European- and US-developed impact assessment methodologies.
LCA was successfully conducted for five seed production units and it was found that the environmental impact for the production of germinated oil palm was not significant. The characterised results of the LCIA for the production of germinated oil palm seeds showed that fossil fuel was the major impact category followed by respiratory inorganics and climate change.
Biosynthesis of plant seed oil is accomplished through the coordinate action of multiple enzymes in multiple subcellular compartments. However, the role of plastid FA transportation during seed oil accumulation has not been evaluated.
The seed size and weight were both increased accordingly. In addition, the seed number per silique and silique number per plant had no changes in transgenic plants. Taken together, our results demonstrated that seed specific overexpression of AtFAX1 could promote oil accumulation in Arabidopsis seeds and manipulating FA transportation is a feasible strategy for increasing the seed oil content.
