title: [Studies on the chemical constituents from Ampelopsis grossedentata].
abstract: 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.
