Ampelopsin, also known as dihydromyricetin, is a flavanol, 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.
Dihydromyricetin shows promise as an alcohol anti-intoxicant.
