title: [Study on chemical constituents in rhizome of Smilax perfoliate].
abstract: OBJECTIVE
  To investigate the components of Smilax perfoliate.
  
  
  METHODS
  The chemical components were isolated by solvent extraction and column chromatography. The chemical structures were identified on the base of physical and spectral data.
  
  
  RESULTS
  Nine compounds were isolated and identified as palmitic acid(I), beta-sitosterol(II), delta 7-5 alpha-cholesten-3-beta-ol(III), naringenin(IV), succinic acid(V), apigenin(VI), resveratrol(VII), daucosterol(VIII) and juncusyl ester B(IX).
  
  
  CONCLUSIONS
  Compound(I), (III), (IV), (VI) and (IX) were obtained from the genus Smilax for the first time.
