| 摘 要： | 针对人参稀有皂苷极性较小的特点，选择超临界二氧化碳流体(SFE-CO2)技术进行提取，最佳提取实验条件为:压力35 MPa,温度50 ℃，夹带剂为70%乙醇，夹带剂用量为1.7 mL/g。 利用高效液相色谱 电喷雾质谱联用分析方法分析其萃取产物，证明该提取方法的提取效率与超声提取接近，且该方法具有环境友好的特点。

| Abstract: | Supercritical CO2 fluid(SFE-CO2) extraction technique was used to extract the rare ginsenosides in processed ginseng, and extracting productions were analyzed by HPLC/ESI-MSn. The optimal extraction conditions were estimated as:the extraction pressure was 35 MPa, the extraction temperature was at 50 ℃， and the concentration of alcohol as entrainer was 70%. The experimental result showed that the extracting efficiency of SFE-CO2 technique is similar with that of transonic extraction. The extracting method using SFE-CO2 technique is in favor of ambient. |
