title: [Comparative analysis of volatile oils of Wuao decoction and its major constituing herbs by GC-MS].
abstract: OBJECTIVE
  To evaluate the correlativity between volatile components of Wuao decoction and its major constituting herbs.
  
  
  METHODS
  The chemical compositions of essential oil, obtained by hydrodistillation from Wu-ao Decoction and its major constituting herbs (Herba Ephedrae, Semen Armeniacae Amarum, Radix Platycodi, Herba Schizonepetae), were analyzed by GC-MS.
  
  
  RESULTS
  The volatile components of Wu-ao Decoction were mostly derived from Herba Ephedrae, Radix Platycodi and Herba Sehizonepetae.
  
  
  CONCLUSIONS
  The method of GC-MS can be used to investigate the volatile component changes in traditional Chinese medicine formulae.
