title: [Phenolic constituents of Ampelopsis grossedentata from zhangjiajie].
abstract: OBJECTIVE
  To study the phenolic constituents from Ampelopsis grossedentata.
  
  
  METHODS
  Compounds were isolated using column chromatographic techniques (silica gel, polyamide gel, Sephadex LH-20) and semi-preparative HPLC. Structures were elucidated on the basis of spectral data (NMR and HR-MS).
  
  
  RESULTS
  Eight compounds were isolated and identified as ampelopsin (I), 5, 7, 3',4',5'-pentahydroxyflavanone (II), galloyl-beta-D-glucopyranoside (III), gallic acid (IV), ethyl gallate (V), myricitrin (VI), (2R, 3S)-5,7,3',4',5'-pentahydroxyflavanonol (VII) and myricetin (VIII).
  
  
  CONCLUSIONS
  Compounds II and VII are obtained from this genus for the first time.
