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 as a laxative; hangover treatment; to treat fever, liver diseases, and parasitic infection; and as a laxative. 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. Dihydromyricetin shows promise as an alcohol anti-intoxicant.
