Cannabis essential oil flower , also known as hemp essential oil , is an essential oil obtained by steam distillation of flowers and leaves on cannabis plants (Cannabis sativa L.) Hemp essential oil different from flaxseed oil, hemp oil and hash oil: the first is a vegetable oil that is pressed from the seeds of low hemp THC varieties, the latter being the extract rich in dried THC (marijuana) or resin (marijuana) flowers.
Pale yellow liquid, essential oil of cannabis flowers is a volatile oil which is a mixture of monoterpene, sesquiterpen, and other terpenoid compounds. A typical aroma of hemp products from about 140 different terpenoids. Essential oils are made from low-THC ("fiber-type") and high-THC ("drug-type") hemp varieties. Since most phytocannabinoids are almost insoluble in water, flax essential oil contains only traces of cannabinoids. Even in the "drug-type" hemp, the THC content of essential oils does not exceed 0.08%.
The essential oil of hemp is used as perfume, cosmetics, soaps, and candles. It is also used as a flavoring food, especially sweets and drinks.

Yield
The results depend on the type of hemp (medicine, fiber) and pollination; gender, age, and part of the plant; cultivation (indoor, outdoor etc.); time and condition of harvest; drying; and storage. For example, fresh shoots of the varieties of Afghani produce 0.29% essential oil. Drying and storage reduces content from 0.29% to 0.20% after 1 week, and becomes 0.13% after 3 months. Monoterpene exhibits far greater losses than sesquiterpenes, but no major component is completely lost in the drying process.
Approximately 1.3 L of essential oil per tonne is produced from freshly harvested outdoor flax, about 10 L/ha. The yield of non-contaminated hemp ("sinsemilla") at 18 L/ha was more than doubled compared with the pollinated hemp (8 L/ha).

Constituent
Sixty-eight components are detected by GC and GC/mass spectrometry (MS) in freshly extracted shoots from high-potential domestic rami. The 57 identified constituents are 92% monoterpenes, 7% sesquiterpenes, and approximately. 1% of other compounds (ketones, esters). The dominant monoterpen is myrcene (67%) and limonene (16%).
In essential oils from outside hemp grow, the concentration of monoterpene varies between 47.9 and 92.1% of total terpenoid content. The sesquiterpenes range from 5.2 to 48.6%. The most abundant monoterpene is? -myrcene, followed by trans-caryophyllene ,? -pinene, trans-ocimene, and? -pinolinene.
Another report says there are 140 terpenoids, dominated by - pinene and limonene which together often comprise 75% of live plant volatiles. However, the extractable essential oil may change in the composition, and the living plants, dried plants and essential oils can smell somewhat differently.
Even in the "drug-type" hemp, the THC content of essential oils is not more than 0.08%.
In the essential oils of five different European flax cultivars, the dominating terpene is myrcene (21.1-35.0%) ,? -pinene (7.2-14.6%), - terpinolene (7.0-16.6%), trans-caryophyllene (12.2.-18.9%), and? -gumen (6.1-8.7%). The main difference between cultivars found in the content? -pinolinene and? -pinene.
Other terpenoids present only in traces are sabinena, - pentinene, 1,8-cineole (eucalyptol), pulegone, - pininene, terpineol-4-ol, bornyl acetate, -copaene, alloaromadendrene, viridiflorene, -bisabolene, ?? -cadinene, trans -? - farnesene, trans-nerolidol, and? -bababolol.
The main alkane present in essential oil obtained by extraction and steam distillation is n-C ?? alkane nonacosane (55.8 and 10.7%, respectively).
Usage
Various terpenes in marijuana have antifungal, antimicrobial, antiviral and insect repellent functions that can be of commercial value when used externally. Else, the (internal) drug may use linalool as an anti anxiety agent/sedative, and myrcene as an analgesic, tranquilizer, anti-inflammatory and muscle relaxant.
