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.
