摘　　要：采用2种不同方法提取香叶树叶的挥发油,分析比较不同的提取方法对挥发性成分的影响。用气相色谱-质谱联用法(GCMS)分析水蒸气蒸馏-萃取法(DSE)和同时蒸馏-萃取法(SDE)2种方法提取香叶树叶挥发油。结果表明,2种方法提取香叶树叶挥发油的化学成分均有差异,水蒸气蒸馏-萃取法提取香叶树叶挥发油鉴定出34种化合物,主要成分为桉树脑,占挥发油总量的38.82%;同时蒸馏-萃取法提取香叶树叶挥发油鉴定出39种化合物,主要成分为桉树脑,占挥发油总量的33.00%。本实验为选择合适的香叶树叶挥发油提取方法提供理论依据。The essential oil ofLindera communis Hemsl leaves was extracted and compared using two different methods.The volatile com- ponents in leaves ofL. communis Hemsl were extracted by distillation-extraction method （DSE） and simultaneous distillation extraction （SDE）, and the components were identified by gas chromatography-mass spectrometry （GC-MS）.The results indicated that volatile com- ponents in leaves ofL. communis Hemsl extracted by the two methods were different. Thirty-four chemical components were identified by DSE, and the major component was eucalyphol accounting for 38.82% of total volatile components. Thirty-nine chemical components were identified by SDE, and the major component was eucalyptol accounting for 33.00% of total volatile components.The appropriate method of extracting the essential oil in leaves ofL. eommunis Hemsl was established in this paper.
