[GC-MS analysis on the chemical constituents of essential oil from bark of Horsfieldia hainanensis].

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.

Conclusion: It has provided scientific foundation for exploitation and utilization of Horsfieldia hainanensis.
