【摘要】 本文用HPLC法分离了复方丹参片中丹参的三种脂溶性成分隐丹参酮、丹参酮Ⅰ_A、丹参酮Ⅱ_A,并用比较法测定其含量。分析条件是,色谱柱YWGC₁₈10μm（5×150mm）,流动相甲醇-水（81.5∶18.5）,流速1ml/min,检测波长UV254nm,进样量10μl。三种丹参酮的回收率在99.5～100.9%,变异系数小于1.0%。共测定了七批样品。更多还原

【Abstract】 The three active principles of Salvia miltiorrhiza （cryptotanshinone, tanshinone Ⅰ_A and tanshinone Ⅱ_A） in compound Salvia miltiorrhiza tablets were determined by reversed phase HPLC. The liquid chromatograph used was a YSB-DZ chromatograph equipped with YSB-Ⅱ pump, DZ-Ⅰ UV detector （fixed wavelength 254nm）, XWT-264 recorder, and a 5×150mm stainless column packed with 10μm YWG C₁₈. The mobile phase was composed of methanol and water （81.5: 18.5）. Flow rate was 1.0ml/min. The recoveries of the method were 99.5～100.1% with a coefficients of variation of 1%. Seven batches of compound Salvia miltiorrhiza tablets were determined.更多还原
