title: [Chemical constituents of Berchemia lineate].
abstract: OBJECTIVE
  To investigate the chemical constituents of the roots of Berchemia lineate as a medicinal plant of Yao nationality in China.
  
  
  METHODS
  Compounds were isolated by various column chromatography and elucidated by physicochemical and spectral analysis.
  
  
  RESULTS
  Nine compounds were isolated from the 95% ethanol extract of the roots of Berchemia lineate and their structures were identified as palmitic acid (1), octadecanoic acid (2), beta-sitosterol (3), stigmasterol (4), fernenol (5), chrysophanol (6), physcion (7), floribundiquinone D (8), 2-acetylphyscion(9) respectively.
  
  
  CONCLUSIONS
  Compounds 1-4,7-9 are isolated from this plant for the first time,and compounds land 2 are firstly isolated from this genus.
