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, as well as in Salix sachalinensis.
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. Methods have been developed to extract ampelopsin from it 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.
In a trial of sixty patients with fatty liver disease dihydromyricetin improved glucose and lipid metabolism and exerted anti-inflammatory effects which were beneficial.
