海南风吹楠皮挥发油化学成分GC-MS分析

GC-MS Analysis on the Chemical Constituents of Essential Oil from Bark of Horsfieldia hainanensis

目的:分析海南风吹楠皮挥发油的化学成分。方法:采用水蒸气蒸馏法提取海南风吹楠皮挥发油,用气相色谱-质谱联用法分析鉴定其化学成分,并应用面积归一法测定各成分的相对百分含量。结果:水蒸气蒸馏提取物得率为0.14%,通过计算机检索、图谱分析鉴定出32个化合物,占总油量的98.62%。海南风吹楠皮主要成分为胡椒烯(25.55%)、1,2,3,5,6,8a-六氢-4,7-二甲基-1-(1-甲乙基)-萘(11.14%)、己二酸,二(2-乙基己基)-酯(8.09%)、油酸(7.04%)等。结论:本实验为开发利用海南风吹楠药用资源提供了科学依据。

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-l-（ 1-meth- ylethyl）-（ 11.14% ） , Hexanedioie acid, bis（2-ethylhexyl） ester （8.09%） , 9-Oetadecenoic acid （7.04%） , etc. Conclusion： It has provided scientific foundation for exploitation and utilization of Horsfieldia hainanensis.
