The definition of CBD
CBD, or cannabidiol, is a pure natural ingredient extracted from hemp plants. The molecular formula of cannabidiol is C21H30O2. The character is white to light yellow resin or crystal, and the melting point is 66℃~67℃. It is almost insoluble in water and soluble in organic solvents such as ethanol, methanol, ether, benzene, and chloroform.
CBD can block the adverse effects of certain polyphenols on the human nervous system, and has a series of physiologically active functions such as blocking breast cancer metastasis, treating epilepsy, anti-rheumatoid arthritis, and anti-insomnia. It is effective for the treatment of multiple sclerosis .
Currently, CBD can be obtained through the following three channels:
Different parts of cannabis plants have different levels of CBD. Taking industrial hemp as an example, the order in descending order of content is: fruit bract leaf, bract leaf, flower, small and tender leaf, old and large leaf, branch, stem, root, fruit. Cannabis biomass with higher content can be used to extract CBD.
CBD can be obtained through chemical synthesis. The CBD obtained by this method is often a mixture of left-handed and right-handed isomers. Due to their close nature, if they need to be separated, the cost is higher.
Recently, some scientists have transferred the gene that produces CBD to E. coli, and this bacterium has the ability to secrete CBD. It can produce CBD by cultivating a large number of bacteria in a similar way to fermentation. This cutting-edge research has a long way to go before large-scale industrial production.
Therefore, at present, the most feasible and economical CBD production method is directly extracted from cannabis plants. Evaporator for CBD extraction is the most intuitive tool.
When it comes to CBD, you can't help but mention THC. They have the exact same molecular formula: 21 carbon atoms, 30 hydrogen atoms and 2 oxygen atoms. But the subtle differences in the way the atoms are arranged cause the two to have different effects on the body.
CBD and THC are chemically similar to endocannabinoids in the human body, which allows them to interact with cannabinoid receptors. This interaction affects the release of neurotransmitters in the brain and internal organs. There are two types of cannabinoid receptors, called CB1 and CB2. CB1 is mainly distributed in the nerve cell epidermis of human brain, central nerve and intermuscular plexus. CB2 is mainly distributed in the nerve cell epidermis of the visceral system. THC mainly activates the CB1 receptor in the body, which makes people feel "high", while CBD plays a certain inhibitory role on the CB1 receptor. Because CBD can affect the metabolism of THC in the human liver, it can greatly reduce the damage of THC to the human body.
CBD and THC have many of the same medical benefits, and they can alleviate several of the same symptoms. However, CBD does not cause the hallucinogenic effects of THC, and there are no side effects of THC.
The falling film evaporator is used in CBD extraction to recover the ethanol. FFE can also separate butane from THC isolation.
