  METHODS
  Essential oil was extracted by water-steam distillation and analyzed by GC-MS.
  
  
  RESULTS
  Two hundreds and ninety chromatographic peaks were detected, among which 111 compounds have been identified. The contents of them made up 90.61% of the total essential oil.
  
  
  CONCLUSIONS
  The main compounds in the essential oil were 3-carene (12.70%), beta-elemene (6.20%), beta-terpinene (3.53%), beta-myrcene (1.97%), gamma-elemene (1.82%), beta-phellandrene (1.65%), and beta-maaliene (1.61%), et al. In addition, suberosin (0.16%), a coumarins compound, was also determined.
