摘　　要：采用同时蒸馏萃取法(SDE)从安徽石台产区的山茱萸中提取挥发油,用气相色谱-质谱(GC-MS)联用技术对提取出的挥发油进行定性与定量分析。SDE法是一种通过同时加热样品液相与有机溶剂至沸腾来实现挥发油提取的前处理技术。用归一化法测定挥发油百分含量,用气相色谱-质谱法对化学成分进行测定,从山茱萸挥发油中共鉴定出48种主要化合物。含量最高的是棕榈酸(28.86%),其次是亚麻酸甲酯(10.82%)。已定性的组分峰面积之和占总色谱峰面积的91.54%。SDE was used to extract essential oil from Fructus Corni of Shi Tai , Anhui province. Qualitative and quantitative analysis were performed by GC-MS. SDE was used to extract essential oil from Fructus Corni. SDE was pre-treatment methods to extract essential oil by heating the sample with organic solvent to boiling . The amount of the components from the essential oil were determined by normalization method. The separated components identified by GC-MS. The results showed that essential oil of Fructus Corni extracted effectively by SDE. Forty eight essential compounds were identified. The highest content was hexadecanoic acid （28. 86% ）, followed by Methyl linolenate （ 10. 82% ）. Components with qualities analyzed was 91.54% of the total essential oil.
