Analysis of Volatile Components in Compound Shengqiyizhi Powder / 中国药师

ABSTRACT

Objective:To analyze the volatile components in compound Shenqiyizhi powder. Methods: The technique of head-space solid phase micro extraction( HS-SPME) with gas chromatography-mass spectrometry ( GC-MS) was applied to study the vola-tile components in the compound powder. The compound essential oil was analyzed by steam distillation( SD) with GC-MS. Results:A total of 117 kinds of volatile components were detected, and among them, 70 kinds of chemical compositions were identified from the compound powder, accounting for 94. 46% of the total volatile components. The component with the highest content wasβ-himachalene followed by ylangene (15. 56%) and β-asarone (7. 36%). Totally 66 kinds of volatile components were detected from the compound essential oil by SD-GC-MS, and among them, 43 kinds were identified, accounting for 77. 41% of the total volatile components. The results indicated that the main volatile components were β-asarone (16. 73%), eugenol methyl ether (6. 74%) and ylangene (5. 81%). Conclusion:The main volatile components in Shenqiyizhi powders areβ-cedrene, ylangene,β-asarone,α-asarone and el-emicin etc. The research can provide scientific basis for the analysis of volatile components.
