General description

Dihydromyricetin is a major flavonoid present in A. grossedentata.

Application

Dihydromyricetin has been used to study its effect on adipogenesis and glucose uptake in differentiated 3T3-L1 pre-adipocytes. It has also been used to study its antitumor activity against liver cancer cells.

Biochem/physiol Actions

Dihydromyricetin (Ampelopsin) is a flavanonol with antioxidant and anti-cancer activity, found to have anti-alcohol intoxication effects. Its anti-alcohol effects appear to be by its actions as a positive modulator of GABA-A receptors at the benzodiazepine site.
Dihydromyricetin possesses anti-inflammatory action.
