The 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 preliminarily concluded that the main constituents were epi 2 pupukeanone(19%), calamenene (7.7%) , cadonene (6.7%) , selilnene(4.3%)
