[摘要] 目的：建立丹参骨宝颗粒水溶性有效成分的质量控制方法。方法：采用薄层色谱法对丹参进行鉴别；采用高效液相色谱法测定主要成分丹参素和丹参酚酸B的含量，色谱柱为Hypersil ODS C18(4.6 mm×250 mm，5 μm)，流动相为甲醇-水-冰醋酸(55∶45∶0.045，V/V)，检测波长为281 nm，流速为1.0 ml/min，柱温为35℃。结果：薄层鉴别斑点清晰，重现性好。高效液相色谱法测定丹参素和丹参酚酸B在3.0～24.0 μg/ml和6.0～48.0 μg/ml线性关系良好(r=0.999 8和r=0.999 9)，平均加样回收率分别为98.2%和99.5%。结论：本实验建立的分析方法灵敏可靠，可作为丹参骨宝颗粒中水溶性有效成分的质量控制。

[Abstract] Objective: To establish a quality control method for hydrophilic active components in Danshen Gubao Granules. Methods: Salvia miltiorrhiza Bge. was identified by thin-layer chromatography, and the deteminations of Danshensu and Salvianic acid B were carried out by high performance liquid chromatography. Separations were performed on a Hypersil ODS C18 (4.6 mm×250 mm, 5 μm) column, the mobile phase was the mixed solvents of methnol-water-glacial acetic acid (55∶45∶0.045, V/V) which set at a flow rate of 1.0 ml/min, and the wave length for UV detection was 281 nm. The temperature was maintained at 35℃. Results: The TLC method was suitable for the identification of Salvia miltiorrhiza Bge.. The linearities for Danshensu and Salvianic acid B were obtained with in the range of 3.0-24.0 μg/ml and 6.0-48.0 μg/ml (r=0.999 8 and r=0.999 9), and the average recoveries were 98.2% and 99.5% respectively. Conclusion: This method is reliable and accurate that it can be used as a quality control method of hydrophilic active components in Danshen Gubao Granules.

丹参为唇形科鼠尾草植物的干燥根部，丹参的有效成分包含脂溶性的蒽醌类成分和水溶性的酚酸类成分[1]。丹参中的有效成分能增加冠脉血流量，降血脂，抑制血栓形成，改善微循环[2-3]，临床常用于心血管疾病的治疗，如市售的复方丹参片、丹参滴丸等。现代药理学研究发现，丹参水溶性活性成分具有抗骨质疏松的作用[4] ......
