title: [Chemical components of essential oils from Flos chrysanthemi Indici in different areas].
abstract: OBJECTIVE
  To provide the foundation for reasonable utilization by analysing the essential oils of Flos chrysanthemi Indici in different areas.
  
  
  METHODS
  The essential oils were extracted by using steam distillation and separated with GC capillary columns. The components were quantitatively determined with normalization method, and were identified with GC-MS.
  
  
  RESULTS
  18, 17 and 20 compounds of essential oils from Guangxi, Guangdong and Hubei were identified.
  
  
  CONCLUSIONS
  There are significant differences among the components and contents of essential oils of Flos chrysanthemi Indici from Guangxi, Guangdong and Hubei.
