| Abstract: | The GC-MS analysis of supercritical CO2 extracting products from Tibetan medicine Rhodiola was discussed in this paper.The GC-MS was used to analyze the product which was extracted under these conditions:the concentration of entrainer is 85%(V/V),the extracting temperature is 55 ℃,the extracting pressure is 30 MPa,the extracting time is 2 h.32 kinds of compounds were identified in the product,which are alcohols,esters,alkanes and alkenes,these account for 87.548% of the total components. |
