title: [Studies on the chemical constituents of Codonopsis pilosula].
abstract: OBJECTIVE
  To study the chemical constituents of Codonopsis pilosula.
  
  
  METHODS
  The compounds were isolated and purified by column chromatography and their structures were elucidated through spectroscopic techniques (NMR) and physicochemical properties.
  
  
  RESULTS
  The compounds were isolated as hesperidin(I), n-hexyl beta-sophoroside(II), atractylenolide III (III), lobetyolin(IV), lobetyolinin(V), taraxerol(VI), taraxeryl acetate(VII), alpha-spinasterol(VIII),9,10,13-trihydroxy-(E)-11-octadecenoic acid (IX),beta-sitosterol(X),beta-daucosterol(XI)and sugar(XII).
  
  
  CONCLUSIONS
  Compounds 1 -2 and 9 are isolated from this plant for the first time.
