Abstract

To study the chemical constituents from Ampelopsis grossedentata (hand-Mazz) W.T. Wang.Chromatography and spectroscopic analysis were employed to isolate and elucidate the chemical constituents in the plant.Seven compounds were isolated and elucidated as ampelopsin (I), myricetin (II), myricitrin (III), gallic acid (IV), beta-sitosterol (V), stigmasterol (VI) and dihydroquercetin (VII).Among these compounds, IV, V, VI and VII were isolated from this plant for the first time, and compound VII was obtained from genus Ampelopsis for the first time.
