title: [Studies on chemical constituents from pine cone of Pinus armandii].
abstract: OBJECTIVE
  To study chemical constituents from pine cone of Pinus annandii.
  
  
  METHODS
  The constituents were isolated by chromatographic method and the structures were identified on the basis of spectral analysis.
  
  
  RESULTS
  Seven compounds were identified as sandaracopimaric acid (I), isodextropimaric acid (II), 12-hydroxyabietic acid (III), dehydroabietic acid (IV), 15-hydroxydehydroabietic acid (V), beta-sitosterol (VI) and daucosterol (VII).
  
  
  CONCLUSIONS
  Compounds I-IV were isolated from this plant for the first time.
