摘　　要：目的:分析山胡椒不同部位的挥发性成分。方法:利用顶空固相微萃取技术(SPME)从山胡椒叶及果实中提取挥发性成分,采用GC-MS联用仪结合保留指数进行鉴定。结果:山胡椒叶挥发油共鉴定出25个化合物,占挥发油总成分的96.51%,主要成分为D-吉玛烯(45.56%)、(+)-喇叭烯(5.76%)、石竹烯(5.75%)等;山胡椒果实挥发油共鉴定出了33个化合物,占挥发油总成分的99.73%,主要成分为β-顺-罗勒烯(31.90%)、可巴烯(12.75%)、α-石竹烯(8.06%)等。二者共有挥发性成分14个。结论:山胡椒叶及果实主要挥发性成分有明显不同。Objective：To analyze the chemical components of essential oil from leaves and fruits of Lindera glauca.Method： The essential oil was collected by solid-phase microextration（SPME）.The chemical constituents were separated and identified by gas chromatography-mass spectrometry（GC-MS） combined with Kovats index.Result： Twenty-five and thirty-three species of chemical components were identified by GC-MS.The content of the identified compounds extracted from leaves and fruits were 96.51% and 99.73% of the total volatile substances,respectively.D-germacrene（45.56%）,（＋）-ledene（5.76%） and caryophyllene（5.75%） were the most abundant volatile compounds released from leaves.The main chemical components of the fruit were（Z）-3,7-dimethyl-1,3,6-octatriene（31.90%）,copaene（12.75%）,α-caryophyllene（8.06%）.Fourteen compounds were owned in both leaves and fruits.Conclusion： The main volatile compounds from leaves of L.glauca are obviously different from fruits.
