title: [Study on the chemical constituent from the dichloromethane extract of the pine needle of Cedrus deodara (II)].
abstract: OBJECTIVE
  To study the chemical constituents of the dichloromethane extract from pine needles of Cedrus deodara.
  
  
  METHODS
  The chemical constituents were isolated and purified from the dichloromethane extract of pine needles by chromatography on silica gel and Sephadex LH-20. Their structures were elucidated by analysis of spectral data and chemical properties.
  
  
  RESULTS
  Seven compounds were isolated and their chemical structures were identified as ferulic acid (1), osthole (2), beta-phenylacrylic acid (3), paeonol (4), beta-sitosterol (5), magnolol (6) and honokiol (7).
  
  
  CONCLUSIONS
  Compounds 1 - 4, 6 and 7 are isolated from this plant for the first time.
