摘　　要：使用不同夹带剂,用超临界CO_2流体萃取丹参中3种丹参酮,研究不同夹带剂的萃取效果。在优化操作条件下萃取丹参中3种丹参酮,HPLC测定萃取物中3种丹参酮的质量分数。3种夹带剂中,95%(V/V)极性物质乙醇效果最好,其次为丙酮、正辛烷。用超临界CO_2流体萃取丹参中3种丹参酮,为了提高萃取率,须使用极性溶剂乙醇作为夹带剂。The extraction effects of different entrainers were investigated with extraction of 3 tanshinones by supercritical CO2 fluid.The 3 tanshinones were extracted from Salvia miltiorrhiza Bge. under the optimal conditions,and the mass fractions of 3 tanshinones in extract were determined by HPLC.The extraction effect of the polar compound 95%ethanol（V/V） was the best among 3 extrainers,and acetone and octane were the second.When 3 tanshinones were extracted by supercritical CO2 fluid,the polar solvent ethanol can be used as entrainers for improvement of extraction rate.
