title: [Chemical constituents of ethyl acetate fraction of Tetrastigma planicaule].
abstract: OBJECTIVE
  To investigate the chemical constituents of ethyl acetate of Tetrastigma planicaule.
  
  
  METHODS
  The ethyl acetate fraction was isolated and purified by repeated silica gel chromatography and recrystallization. The structures of compounds were identified by physical-chemical methods and spectral data such as MS, 1H-NMR, 13C-NMR, etc.
  
  
  RESULTS
  Six compounds were identified as gheddic acid (I), tricosanol (II), beta-sitosterol (III), palmitic acid (IV), ethyl gallate (V) and vanillin (VI), respectively.
  
  
  CONCLUSIONS
  Compounds I, II, V and VI are isolated from this plant for the first time.
