[Studies on the chemical constituents from Ampelopsis grossedentata].
OBJECTIVE
To study the chemical constituents from Ampelopsis grossedentata (hand-Mazz) W.T. Wang.


METHODS
Chromatography and spectroscopic analysis were employed to isolate and elucidate the chemical constituents in the plant.


RESULTS
Seven compounds were isolated and elucidated as ampelopsin (I), myricetin (II), myricitrin (III), gallic acid (IV), beta-sitosterol (V), stigmasterol (VI) and dihydroquercetin (VII).


CONCLUSIONS
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.
