title: [GC-MS analysis of essential oils from rhizomes of Atractylodes lancea (Thunb.) DC. and A. chinensis (DC.) Koidz].
abstract: OBJECTIVE
  To analyze the constituents from the rhizomes of Atractylodes lancea and A. chinensis in essential oils.
  
  
  METHODS
  GC-MS method was used.
  
  
  RESULTS
  32 and 29 compounds were identified respectively.
  
  
  CONCLUSIONS
  The main constituents in the essential oils from the rhizome of A. chinensis are beta-eudesmol or a mixture of beta-eudesmol and atractylone, whereas from that of A. lancea are hinesol, a mixture of beta-eudesmol and atractylone, and atractylone.
