Analysis of the Volatile Constituents of the Compound Extract from 3 Medicinal Materials in Siji Ganmao Tablet by Supercritical CO2 Fluid Extraction / 中国药房

ABSTRACT

OBJECTIVE:To study the volatile constituents of the compound extract from Folium Perillae,Pericarpium Citri and Herb Schizonepetae in Siji Ganmao tablet by supercritical CO2 fluid extraction (SFE-CO2). METHODS:Supercritical CO2 ex-traction technology was used to extract the volatile constituents of 3 medical material in Siji Ganmao tablet. The chemical constitu-ents of the compound extract from 3 medicinal materials were analyzed by GC-MS. RESULTS:The extracting rate of SFE-CO2 was 2.21%,21 compounds in the compound extract were separated and 16 compounds were identified with the major components of si-nensetin(36.56%)and linolic acid(19.52%). The extracting rate of water steam distillation(SD)was 1.035%,51 compounds in the compound extract were separated and 32 compounds were identified with the major components of D-limonene(62.40%) and thujone(15.49%). CONCLUSIONS:The volatile constituents of F. perillae,P. cCitri and H. Schizonepetae can be compound ex-tracted by SFE-CO2,however,it is different from the constituents of the compound volatile oil by SD.
