title: [GC-MS analysis on the chemical constituents of essential oil from bark of Horsfieldia hainanensis].
abstract: OBJECTIVE
  To analyze the constituents of the essential oil from the bark of Horsfieldia hainanensis.
  
  
  METHODS
  The volatile oil was obtained by steam distillation. The chemical constituents were separated and identified by gas chromatography-mass spectrometry (GC-MS). The relative contents were determined by area normalization.
  
  
  RESULTS
  The extraction rate of the bark of Horsfieldia hainanensis was 0.14%. 32 compounds were separated and identified, which accounted for 98.62% of the essential oil. The main chemical components of the essential oil were Copaene (25.55%), Naphthalene, 1,2,3,5,6,8a-hexahydro-4,7-dimethyl-1-(1-methylethyl)-(11.14%), Hexanedioic acid, bis(2-ethylhexyl) ester (8.09%) , 9-Octadecenoic acid (7.04%), etc.
  
  
  CONCLUSIONS
  It has provided scientific foundation for exploitation and utilization of Horsfieldia hainanensis.
