title: [Chemical constituents of Cichorium intybus L].
abstract: OBJECTIVE
  To investigate the chemical constituents of Cichorium intybus.
  
  
  METHODS
  Constituents were separated by means of solvent extraction and chromatography on silical gel. The structures were established by spectral analysis and chemical evidence.
  
  
  RESULTS
  Seven compounds were isolated from the roots of C. intybus and four of them were identified as alpha-amyrin, taraxerone, baurenyl acetate and beta-sitosterol.
  
  
  CONCLUSIONS
  All the four compounds were obtained from the plant for the first time.
