中文摘要：

目的：对中药复方制剂心可宁滴丸中的丹酚酸B进行含量测定。方法：采用高效液相色谱法，以乙腈-0．1％磷酸水液（21．5：78．5）为流动相；检测波长为286nm。结果：丹酚酸B在0．196～1．960μg范围内均与色谱峰面积呈良好的线性关系，r为0．99996，平均加样回收率为97．83％（N=5），RSD=3．33％。结论：本方法快速简便，灵敏度和稳定性高，为心可宁滴丸的质量标准奠定了良好的基础。

英文摘要：

Objective： To establish a method to determine salvianolic acid B in xinkening drop pills. Methods： The Rp-HPLC method was applied with Acetonitrile and 0. 1% H3PO4 water as mobile phase（21. 5178. 5）, with detection wavelength at 286nm. Results： In the range from 0. 196 to 1. 960μg, salvianolic acid B was in a good line with chromatograph peaks area,r=0. 9996, the average recovery ratio is 97. 830% （N= 5） ,RSD= 3.33 %. Conclusions： The method is quickly simple with a high intelligent degree and stabilities. The method could be used to control quality effectively as a good base.
