目的　建立高效液相色谱法测定乳块消片中丹参素的含量方法。方法　以甲醇 -水 -乙腈-冰醋酸 (8∶92∶0 5∶1)为流动相 ;检测波长为 2 80nm。结果　丹参素在 0 13～ 1 96 μg范围内线性良好 (r =0 9998)。平均回收率为 10 1 19% ,RSD为 2 92 %。结论　本方法简便 ,结果准确 Objective To establish a HPLC method for the determination of danshensu in Rupixiao Tablets. Methods The mobile phase consisted of methanol-water-acetonitrile-glacial acetic acid (8:92∶0 5∶1); the detection wavelength was 2 80nm. Results The linearity of Danshensu was good in the range of 13-13 μg (r = 0 9998). The average recovery was 10 1 19% with an RSD of 2 92%. Conclusion This method is simple and accurate
