title: [Analysis of volatile oil in herb of pimpinella candolleana by SPME-GC-MS].
abstract: OBJECTIVE
  To analyze components of volatile oil from the herb of Pimpinella candolleana.
  
  
  METHODS
  The components of volatile oil were investigated by SPME-GC-MS.
  
  
  RESULTS
  Sixty-five compounds were identified which accounted for 92. 17% of total volatile oil.
  
  
  CONCLUSIONS
  The main constituents in the essential oil were alpha-zingiberene (24.82%), pregeijerene (16.27%), beta-bisabolene (4. 82%), 2-isopropyl-5-methyl-9-methylene-bicyclo [ 4. 4. 0] dec-l-ene (4.03%), beta-sesquiphellandrene (3.98%), trans-beta-farnesene (3.68%), ar-curcumene (3.54%).
