Ampelopsin, also known as dihydromyricetin, is a flavanonol, a type of flavonoid. It can be found in Cedrus deodara[1] or in the Japanese raisin tree (Hovenia dulcis).[2][3] It is also found in Erythrophleum africanum.[4]

The compound is credited with hepatoprotective effects observed in rodents.[5] Use of Hovenia species in traditional Chinese herbal medicine as a hangover cure has led to research into the potential action of dihydromyricetin in counteracting the effects of alcohol in the brain.[2][6][7]
