Dihydromyricetin, also know as Ampelopsin, is a flavanonol, a type of flavonoid. It is found in the Ampelopsis species japonica, megalophylla, and grossedentata; Cercidiphyllum japonicum; Hovenia dulcis; Rhododendron cinnabarinum; some Pinus species; and some Cedrus species, as well as in Salix sachalinensis. Hovenia dulcis has been used in traditional Chinese medicines to treat fever, parasitic infection, as a laxative, and a treatment of liver diseases, and as a hangover treatment.
1. Antibacterial effect: pharmacological experiments show that dihydromyricetin is effective against Bacillus subtilis, Staphylococcus aureus, Salmonella, Escherichia coli, Aerobacter, Saccharomyces cerevisiae, Rhodotorula glutinosa, Penicillium, Aspergillus niger, Aspergillus flavus , Mucor and Rhizopus have antibacterial effects, especially for Gram-positive, Gram-negative cocci or bacilli.
2. Regulating effect on blood sugar and blood lipids
Liver protection: Dihydromyricetin has a significant protective effect on carbon tetrachloride toxic damage of rat hepatocytes cultured in vitro, and D2 galactosamine and lipopolysaccharide-induced liver damage in mice.
3. Antioxidant effect: Dihydromyricetin can obviously inhibit the formation of MDA in oils. With the increase of the purity of dihydromyricetin (60%~90%), the antioxidant effect is enhanced; it has strong resistance to animal oils and vegetable oils.
4. Antioxidant oxidation.
5. Anti-tumor effect: In recent years, anti-tumor pharmacodynamics studies have found that one of its active ingredients, the small molecule compound of vitis has a relatively strong anti-cancer effect.
