目的建立HPLC法测量鉴定丹参素钠在芪胶囊中的含量。方法使用反相高效液相色谱的方法,使用Thermo BDS HYPERSIL C_(18)(250 mm×4.6 mm)色谱柱,以甲醇-冰醋酸-水(5:1:94)为流动相,流速1.0 ml·min~(-1),检测波长281 nm。结果丹参素钠在12.5~250μg·ml~(-1)范围内线性关系良好,其线性方程为y=11357x-2567(r=0.9999)。98.74%为丹参素的平均回收率,RSD=0.41%(n=6)。结论 HPLC法简单方便、安全可靠、准确度高,可作为该制剂的质量控制方法。
Objective To establish an HPLC method for the determination of sodium danshensu in Qiqi capsule. Methods The mobile phase consisted of methanol - glacial acetic acid - water (5: 1: 94) and the flow rate was 1.0 ml on a Thermo BDS HYPERSIL C 18 (250 mm × 4.6 mm) column using reverse phase high performance liquid chromatography · Min ~ (-1), detection wavelength of 281 nm. Results Sodium danshensu showed a good linearity in the range of 12.5 ~ 250μg · ml ~ (-1) with a linear equation of y = 11357x-2567 (r = 0.9999). 98.74% for the average recovery of danshensu, RSD = 0.41% (n = 6). Conclusion HPLC method is simple and convenient, safe and reliable, with high accuracy, which can be used as the quality control method of the preparation.
