摘　　要：本研究以超临界CO2萃取后的红景天干粉乙醇常温浸提液中的红景天甙为纯化对象,采用大孔树脂对纯化工艺进行了系统的研究,并得出初步纯化红景天甙的最佳工艺路线。其工艺参数为:树脂类型:NKA-Ⅱ;树脂用量:5mg红景天甙/g干树脂;解吸剂:二氯甲烷:乙醇=7:3;解吸剂流速:2倍柱体积/h;解吸剂用量:16ml/g干树脂。通过此纯化工艺可将红景天甙初步纯化到40%,解吸率为98.02%。With alcohol extracting solution of Rhodiola sachalinensis powder processed by supercritical CO2 extraction, the purification process of salidroside was studied with resin. The optimal process conditions were： the kind of resin NKA- Ⅱ, the consumption of resin 5mg（salidroside）/g（dry resin）, the strippant ratio of methylene dichloride to ethanol 7：3, the flow rate of strippant 2 times volume of column/h and the consumption of strippant 16ml/g（dry resin）. The purity of salidroside can reach 40% by this purification process. The ratio of stripping is 98.02%.
