Abstract:

Two extracts were obtained from Zanthoxylum bungeanum by supercritical CO2 extraction method under low and high pressure conditions, respectively. Then their chemical components were detected by GC-MC, and their relative contents were analyzed by chromatographic peak area normalization method. The results showed that the yield of low pressure extraction is 5.0%, and there are 50 kinds of chemical components but no polyene amides in the extract; while the yield of high pressure extraction is 2.0%, and there are 13 kinds of chemical components in the extract and the content of polyene amides is higher.

Key words: supercritical CO2, Zanthoxylum bungeanum, separation, volatile oil, sanshool
