title: [Study on the constituents of essential oil of Shunaoxin dropping pills by GC-MS].
abstract: OBJECTIVE
  To study the constituents of essential oil from Shunaoxin dropping pills by GC-MS.
  
  
  METHODS
  The essential oil from Shunaoxin dropping pills were extracted by absolute alcohol and analyzed by GC-MS.
  
  
  RESULTS
  15 components from the essential oil of Shunaoxin dropping pills were identified.
  
  
  CONCLUSIONS
  The main components in the essential oil of Shunaoxin dropping pills are lactones such as Z-ligustilide, senkyunolide A,3-butylphthalide and 3-butylidenephthalide, other components are organic acids such as ethyl linoleate, 9,12-octadecadienoic acid and ethyl palmitate.
