摘　　要：采用水蒸气蒸馏法和同时蒸馏萃取法提取了山胡椒果实的挥发油,并利用气相色谱-质谱联用技术(GC-MS)分析和鉴定其化学成分。结果表明从山胡椒果实挥发油中共鉴定出60种化合物,其中从水蒸气蒸馏法提取的山胡椒挥发油中鉴定出38种化学成分,从同时蒸馏萃取法提取的山胡椒挥发油中鉴定出56种化学成分。山胡椒挥发油中主要成分为β-月桂烯、D-柠檬烯、桉树脑、香茅醛、柠檬醛、芳樟醇、β-石竹烯等。将这两种提取方法结合,可更全面的评价山胡椒挥发油的化学成分。The essential oil obtained by direct distillation extraction （DDE） and simultaneous distillation extraction（SDE）, the chemical compositions were analyzed by GC-MS. Results demonstrated that 60 components were identified in L. cubeba essential oils by GC-MS, of which, 38 were contained in essential oil extracted by DDE and 56 in essential oil extracted by SDE. The major compounds in L. cubeba essential oil were β-myrcene, D-limonene, eucalyptol, citronellal, 3,7-dimethyl-2,6-Octadienal and linalool, β-Caryophyllene, et al. The combination of both extraction methods can help obtain a more comprehensive compositions for L. cubeba essential oil.
