THC and CBD are the two most abundant naturally occurring Unlike Cannabidiol, THC is a psychoactive compound (meaning it affects brain. Different cannabis strains produce different results, meaning that while one strain is great for glaucoma, another type of medical cannabis may. THC & CBD are both from the cannabis plant, but how are they different? Learn more about CBD and its unique medical benefits that gave rise to its popularity.

These standard curves were used to estimate the concentrations of the above analytes in the extracts. Commercial hemp seeds are marketed for their high nutritional values, but due to their relationship to Cannabis spp. Hemp seeds from three brands in local supermarkets were purchased and brought to the laboratory. Each brand of hemp seeds was subjected to four different extraction protocols, and each protocol was repeated thrice to account for any variability due to the extraction procedures and associated errors.
As it is common in the Cannabis spp. Extraction methods employed in this investigation utilize somewhat different principles to extract the phytocannabinoids from the hemp seeds into the solvent. This extraction process is also expected to offer high solubility to the phytocannabinoids due to heating to higher temperatures. Sonication was conducted at an ambient temperature using ethanol as the solvent, and is expected to help release compounds from the plant materials.
Among these four methods, one would anticipate the highest yield of phytocannabinoids from Soxhlet extraction. Since ethanol was used in all these extraction methods, differences in extracted quantities of phytocannabinoids can be attributed to the extraction methods themselves.
We observed large standard deviations associated with each extraction of the same brand of seeds. Each extraction was performed thrice to be able to assess the experimental variability during extraction, and based on this large standard deviation, it appears that the extracts could show reasonable variability in the assessed phytocannabinoids, and this deviation may also be due to the nonhomogenous hemp seed bulk material.
Either way, these variations warrant the analysis of multiple samples of hemp seed from different parts of the bulk material to assess total amount of phytocannabinoids, as accurately as possible.
Total CBD is expected to be relatively higher in concentration in hemp seeds and is reflected in these measurements. It is interesting to note that a different brand led to a completely different profile in the phytocannabinoid variations brand 1 vs.
For brand 3, three extraction methods concurred with the estimation of the phytocannabinoids, viz. It is also noted that the phytocannabinoid content exhibited a significant variation even among batches from the same brand, reflecting both the inhomogeneous nature of seeds as well as the variations in quantification based on the extraction process. Using a similar hexane-sonication procedure, quantification conducted by Ross et al.
This inconsistency could be attributed to the higher oil content within hemp seeds compared to the rest of plant. In an earlier study, Ross et al. In the report by Chinello et al. This suggests the importance of heating and prolonged solvent cycling in extracting phytocannabinoids from lipid-rich materials such as hemp seeds.
A more robust extraction methodology such as Soxhlet extraction may be more appropriate for the testing of hemp seed products. One may also consider employing washing of hemp seeds with ethanol or other similar solvents, to remove any contamination to the seeds before packaging; but such change from current practice and new processes must be thoroughly investigated before implementation for consumer marketing.
Based on the above findings, it is also recommended that the hemp seeds be analyzed specifically for phytocannabinoid content before release into consumer markets. Cite this article as: National Center for Biotechnology Information , U.

In terms of physical differences, indica plants are darker, shorter and bushier than sativas, which are tall and lean. A third species, Cannabis ruderalis , is rarely cultivated. Hybrid strains, which can be indica- or sativa-dominant, are bred to combine desired traits from their parent plants. The higher that number is, the more potent the product. They also contain the highest proportion of cannabinoids in the plant. Rather than being bright and pretty like roses or daisies, cannabis flowers look more like clumps of dried oregano.
Cannabis oil, which will also be available on Oct. In addition to dried cannabis flowers and cannabis oil, fresh cannabis, live cannabis plants and cannabis seeds have also been authorized for sale on Oct. This brownish substance has been used for centuries across Asia. Because vaporizing does not combust the entire flower, some believe it is somewhat better for your lungs than smoking, much like e-cigarettes are when compared to traditional cigarettes.
Such products are usually made with dried cannabis flowers or cannabis oil.
From 'sativa' to 'CBD,' common cannabis terms you need to know
CBD can actually lessen or neutralize the psychoactive effects of THC, depending on how much of each compound is consumed. Thus, it stands to reason that “modulating endocannabinoid system activity may have . Cannabis plants. The cannabis plant contains dozens of cannabinoids. The most well known cannabinoid for a long time has been tetrahydrocannabinol (THC). “Hemp” primarily refers to cannabis plants raised for commercial The plants' leaves, stalk and stems are seldom consumed recreationally.
