分别采用水蒸气蒸馏法(HD)和微波辅助水蒸气蒸馏法(MAHD)提取鸦胆子挥发油。运用毛细管气相色谱-质谱联用仪结合计算机检索对所得挥发油成分进行分析和鉴定,用气相色谱面积归一法测定各组分的相对质量分数。结果显示,两种方法分别从鸦胆子挥发油中鉴定出42种和37种化合物,分别占总峰面积的94.09%和94.13%。不同方法所得鸦胆子挥发油化学组成不同,但主要成分是黄樟脑、(+)-4-蒈烯、β-香叶烯、丁香油酚甲醚、2,6-二甲氧基甲苯、柠檬烯和甲基胡椒酚。
Brucea javanica extract was extracted by steam distillation (HD) and microwave assisted steam distillation (MAHD) respectively. The components of volatile oil were analyzed and identified by capillary gas chromatography-mass spectrometry combined with computer search. The relative mass fraction of each component was determined by gas chromatography area normalization. The results showed that 42 kinds and 37 kinds of compounds were identified respectively from the volatile oil of Brucea javanica, accounting for 94.09% and 94.13% of the total peak area respectively. The chemical composition of the volatile oil of Brucea javanica obtained by different methods is different, but the main constituents are safrole, camphor, (+) - 4-carene, β-myrcene, eugenol methyl ether, 2,6-dimethoxytoluene, Methyl piperol.
