title: [Study on the effects of different compatibility of guizhi decoction on component of volatile oil from Cinnamomum cassia by GC-MS].
abstract: OBJECTIVE
  To study the changes of volatile oil from different compatibility of Guizhi decoction and explore their connection.
  
  
  METHODS
  The volatile oil of Cinnamomum cassia and different compatibility of Guizhi decoction extracted by steam distillation were analyzed by GC-MS.
  
  
  RESULTS
  The main components of volatile oil in Cinnamomum cassia were found in different compatibility of Guizhi decoction and they accounted the most amount of total volatile oil,but the contents of the main components were decreased, there were more components existed in different compatibility of Guizhi decoction than those in Cinnamomum cassia, the new components came from Zingiber officinale mostly.
  
  
  CONCLUSIONS
  GC-MS can be used to reflect the changes of volatile oil from different compatibility of Guizhi decoction, and the result will provide some evidence for the research of regular pattern of compatibility in Guizhi decoction.
