摘　　要：以同时蒸馏萃取法（ＳＤＥ）提取了药用皖鄂鼠尾草精油，用毛细管ＧＣ／ＭＳ／ＤＳ联用仪分离并初步鉴定了其中的３５种化合物，占总峰面积的８７％；再用气相色谱－傅里叶红外光谱联用技术、双柱程序升温保留指数和标样核对等方法鉴定了１９种化合物，占总峰面积的２５％。初步确定含量较高的组分是Ｅｐｉ－２－ｐｕｐｕｋｅａｎｏｎｅ（１９％），去氢白菖烯（７．７％），δ－荜澄茄烯（６．７％），（＋）－δ－瑟林烯（４．３％）。讨论了对此种样品鉴定成功率较低的原因。The essential oil in medicinal plants of Salvia paramiltiorrhiza H. was extracted by simultaneous distillation extraction(SDE) method. The components of the essential oil were analyzed by means of capillary gas chromatography and combined GC/MS/DS. Thirty five constituents of the essential oil were identified by GC/MS/DS on SE 54 and PEG 20M columns. Of these components, nineteen were further identified by dual column temperature programmed retention indexes, GC/FTIR as well as the corresponding authentic samples. It can be preliminarily concluded that the main constituents were epi 2 pupukeanone(19%), calamenene (7.7%) , cadonene (6.7%) , selilnene(4.3%)
