Abstract: The essential oil in medicinal plants of Salvia paramiltiorrhiza H. was extracted by simultaneous distillationextraction(SDE) method. The components of the essential oil wereanalyzed 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 thesecomponents, nineteen were further identified by dual columntemperature-programmed retention indexes, GC/FTIR as well as thecorresponding authentic samples. It can be preliminarily concludedthat the main constituents were epi-2-pupukeanone(19%), calamenene(7.7%), cadonene(6.7%), selilnene(4.3%).

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。
