摘　　要：以薄荷原油为原料 ,借助超临界CO2 萃取技术对其中薄荷醇进行提纯 .实验结果表明 ,较好的萃取参数压力为 :9.0～ 9.5MPa、温度 3 5～ 4 5℃ .提高薄荷醇纯度 ,可缩短通过冷冻结晶提取薄荷醇的时间 .Peppermint alcohol in peppermint crude oil was puried by means of supercritical CO 2 extraction. The experimental results indicated that the better ranges of extraction parameters are 9.0～9.5 MPa for pressure and 35～45 ℃ for temperature. The increase of peppermint alcohol content in peppermint oil saves extracting time during freezing crystallization and improves production efficiency.
