Ampelopsin, also known as dihydromyricetin, 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,[1] as well as in Salix sachalinensis.[2]
Hovenia dulcis has been used in traditional Japanese, Chinese, and Korean medicines to treat fever, parasitic infection, as a laxative, and a treatment of liver diseases, and as a hangover treatment.[3] Methods have been developed to extract ampelopsin at large scales, and laboratory research has been conducted with the compound to see if it might be useful as a drug in any of the conditions for which the parent plant has been traditionally used.[3]
