以乙醚和二氯甲烷为提取溶剂,采用同时蒸馏萃取法(SDE)提取了白兰花挥发油,用气-质联用法(GC-MS)分别鉴定出84种和81种化学成分,分别占白兰花挥发油总峰面积的97.47%和97.31%。对比两种溶剂萃取结果,共有69种化合物相同,其中含量较高的物质有:芳樟醇(65.10%,65.27%)、2-甲基丁酸甲酯(4.96%,6.62%)、2-甲基丁酸(1.98%,3.14%)、丁子香酚甲醚(2.22%,2.43%)、α-甲基-α-[4-甲基-3戊烯基]、环氧乙烷甲醇(2.52%,1.67%)。
The volatile oil of white orchid was extracted by simultaneous distillation extraction (SDE) using diethyl ether and dichloromethane as extraction solvents, and 84 and 81 chemical constituents were identified by gas chromatography-mass spectrometry (GC-MS) The total peak area of volatile oil 97.47% and 97.31%. Comparing the two solvent extraction results, a total of 69 compounds were the same. Among them, the higher contents of linalool (65.10%, 65.27%), methyl 2-methylbutyrate (4.96%, 6.62% Methylbutyric acid (1.98%, 3.14%), eugenol methyl ether (2.22%, 2.43%), α-methyl- α- [4-methyl-3-pentenyl] 2.52%, 1.67%).
