Natural Products

Natural products refer to the constituents or metabolites of animals, plant extracts (abbreviated as plant extracts) or insects, marine organisms and microorganisms, as well as many endogenous chemical components in humans and animals, collectively referred to as natural products, of which the main Including proteins, peptides, amino acids, nucleic acids, various enzymes, monosaccharides, oligosaccharides, polysaccharides, glycoproteins, resins, colloids, lignin, vitamins, fats, fats, waxes, alkaloids, volatile oils, flavonoids, glycosides , Terpenes, phenylpropanoids, organic acids, phenols, quinones, lactones, steroids, tannic acids, antibiotics and other naturally occurring chemical components.

Quinone Ring

Quinone rings are a class of chemical components with quinoid structure in traditional Chinese medicine. They are mainly divided into four types: benzoquinone, naphthoquinone, phenanthrenequinone, and anthraquinone. Anthraquinone and its derivatives are particularly important in Chinese medicine. Quinone rings are widely distributed in plants.

Lignans

Lignans is a type of natural component formed by the bimolecular polymerization of phenylpropanin. There are four types of monomers that make up lignans: cinnamic acid and occasionally cinnamaldehyde. Cinnamyl alcohol. Acrylic benzene. Allylbenzene. The substance exists in plants and belongs to a phytoestrogen, which has the effect of scavenging free radicals in the body and anti-oxidation.

Steroids

Steroids are a general term for a large class of cyclopentanic fully hydrogenated phenanthrene derivatives widely distributed in the biological world. Also known as steroids and steroids. Steroid compounds do not contain bound fatty acids and are non-saponifiable lipids; these compounds are isoprenoid substances, which are generated by triterpene cyclization and then internal molecular reorganization and chemical modification. Steroids include steroids, bile acids and bile alcohols, steroid hormones, insect ecdysone, cardiac glycosides and saponins, and toad poison.

Coumarin

Coumarin, found naturally in black cougar, whiff chrysanthemum, wild viburnum, and orchid, has fresh hay and coumarin flavors, and is generally not eaten, and is allowed for tobacco and external use. Mainly divided into: simple, furan, pyran, double coumarin, isocoumarin and other coumarin.
