title: [The volatile components of three radix et rhizoma asari].
abstract: OBJECTIVE
  To analyze and compare the volatile components of Asarum sieboldii Miq, Asarum himalaicum Hook. F. et Thoms and Asarum. debile Franch in the same area.
  
  
  METHODS
  The volatile components were extracted from three Radix et Rhizoma Asari by solid-phrase microextraction and their contents were analyzed by gas chromatography-mass spectrometry (GC-MS).
  
  
  RESULTS
  59, 99 and 85 volatile components were identified from Asarum sieboldii Miq, Asarum himalaicum Hook. F. et Thoms and Asarum debile Franch, representing the ralative content of 82.75% - 99.43% of the volatile oil. 16 of same components were identified in the three Radix et Rhizoma Asari, and the contents of the same components were different among them. In addition, some unique components were identified in them respectively.
  
  
  CONCLUSIONS
  There were differences among the chemical components and the contents of the volatile oil of the three Radix et Rhizoma Asari. The results could give certain reference value for the medicine whether Asarum himalaicum Hook. F. et Thoms and Asarum debile Franch can replace Asarum sieboldii Miq.
