title: [Study on the chemical constituents from pine needles of Cedrus deodara].
abstract: OBJECTIVE
  To study the chemical constituents from pine needles of Cedrus deodara.
  
  
  METHODS
  Chemical constituents were isolated by silica gel and Sephadex LH-20 column chromatography. The structures of the isolated compounds were elucidated through spectroscopic analysis.
  
  
  RESULTS
  The compounds were identified as 9-hydroxy-dodecanoic acid (I), ethyl laurate (II), ethyl stearate (III), 3beta-hydroxy-oleanolic acid methyl ester (IV), beta-sitosterol (V), shikimic acid (VI), methylconiferin (VII), ferulic acid beta-glucoside (VIII).
  
  
  CONCLUSIONS
  Compounds I-IV, VI-VIII are isolated and identified from this genus for the first time, compound V is isolated from pine needles of this genus for the first time.
