摘要
探讨了藏药红景天超临界流体萃取物的GC-MS分析。结果表明,对红景天在萃取剂乙醇浓度为85%、萃取温度55℃、萃取压力30 MPa、萃取时间2 h条件下的萃取物成分进行GC-MS分析,共鉴定出32种组分,占出峰物质总量的87.548%,主要为醇类、酯类、烷烃、烯烃等化合物。
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.
