紫玉兰叶油化学成分的气相色谱/质谱法分析

Analysis of Chemical Constituents of Essential Oil in Purple Magnolia Leaves by Gas Chromatography-Mass Spectrometry

采用常规水蒸汽蒸馏法提取出紫玉兰叶油，经气相色谱．质谱联机分析，分离出４０多个峰，鉴定出３２种化合物，主要是大根香叶烯、檀紫三烯、石竹烯、３，７－二甲基一１，３，７－辛三烯、莰烯等，占总峰面积的９５％。

The essential oil in purple magnolia leaves was extracted by steam distillation approaches. The Oil Obtained was dried with anhydrous magnesium sulfate. According to the analysis of gas chromatography/mass spectrometry, more than 40 peaks were separated and 32 compounds were identified. The identified constituents represent 95% of the peak area of the essential oil. The main compounds were germacrene-D, santolina triene, caryophyllene, l, 3, 7-octatriene, 3, 7-dimethyl, and camphene, etc.
