Preliminary analysis of the essential oil in medicinal plants of salvia paramiltiorrhiza H.

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 preliminary concluded that the main constituents were epi-2-pupukeanone (19%), calamenene (7.7%), cadonene (6.7%), selilnene (4.3%).EI02142-1463
