| 摘 要： | 对超临界CO2 萃取甘肃产党参中脂溶性成分的工艺进行研究。采用单因素试验方法，以收膏率和总皂苷元得率为指标考察粒度、萃取压力、萃取温度、萃取时间对党参萃取效率的影响。结果表明，粒度380～250μm的党参，在压力30MPa、温度65℃、二氧化碳流速2L/min 条件下萃取时间2h，得到收膏率为1.11%，总皂苷元得率为2.23‰。用超临界CO2 萃取党参中脂溶性成分可行。

| Abstract: | Lipid-soluble components in the roots of Codonopsis pilosula were extracted with supercritical carbon dioxide, and the effects of material particle size, extraction pressure and temperature and length of extraction on the yields of crude extract and total saponins were investigated. The optimum conditions for the extraction of lipid-soluble components were determined to be: material particle size 380－250μm, extraction pressure 30 MPa, carbon dioxide flow rate 2 L/min and length of extraction 2 h. Under these optimum conditions, the yields of crude extract and total saponins were 1.11% and 2.23‰, respectively. |
