title: [Analysis of volatile composition of different specification of Panax notoginseng].
abstract: OBJECTIVE
  To analyse the volatile compositions of different specification of Panax notoginseng.
  
  
  METHODS
  Volatile compositions from different specification of Panax notoginseng were detected by Headspace Solid-Phase Micro-Extraction with GC/MS.
  
  
  RESULTS
  Terpenoids were the main compositions in different specification of Panax Notoginseng, and a-guaiene was the fundamental ingredient. The type, content and quantity of the compounds were different in different type of Panax notoginseng.
  
  
  CONCLUSIONS
  Terpenoids were the main pharmacodynamics of the volatile compositions of Panax notoginseng and worthy of further study.
