摘要:目的 建立高效液相色谱法同时测定痛经灵颗粒中丹酚酸B、芍药苷和羟基红花黄色素A含量的方法,为有效控制其质量提供可靠的方法。方法 采用Welchrom C18色谱柱,以乙腈(A)-0.1%磷酸(B)为流动相梯度洗脱,流速1.0 mL/min,检测波长为230 nm。结果 丹酚酸B在0.197~1.316 μg范围内呈良好的线性关系(r=0.999 6),平均回收率为98.72%,RSD=1.49%;芍药苷在0.158~1.051 μg范围内呈良好的线性关系(r=0.999 8),平均回收率为99.01%,RSD=0.92%;羟基红花黄色素A在0.053~0.353 μg范围内呈良好的线性关系(r=0.999 4),平均回收率为98.34%,RSD=1.60%。结论 该方法简便、灵敏、准确、重复性好,可用于痛经灵颗粒的质量控制。

Abstract: Objective To establish a simultaneous determination method for Salvianolic acid B, Paeoniflorin and Hydroxysafflor yellow A in Tongjingling Granules; To provide a reliable method for effective quality control. Methods The determination was performed on a Welchrom C18 column with acetonitrile (A) - 0.1% phosphoric acid (B) as the mobile phase in gradient elution mode at the flow rate of 1.0 mL/min. The detection wavelength was 230 nm. Results Salvianolic acid B presented in a good linear relation in the range of 0.197–1.316 μg, and the average recovery rate was 98.72% with RSD 1.49%; Paeoniflorin presented in a good linear relation in the range of 0.158–1.051 μg, and the average recovery rate was 99.01% with RSD 0.92%; Hydroxysafflor yellow A presented in a good linear relation in the concentration range of 0.053–0.353 μg, and the average recovery rate was 98.34% with RSD of 1.60%. Conclusion This method is simple, sensitive, accurate and with good reproducibility, which can be used for quality control of Tongjingling Granules.

痛经灵颗粒收载于《中华人民共和国卫生部药品标准·中药成方制剂》第十五册,由丹参、赤芍、香附(醋制)、蒲黄、红花、延胡索、乌药等组成,具有活血化瘀、理气止痛功效,临床用于治疗气滞血瘀所致痛经。该产品现行标准中没有含量测定项[1],无法有效控制其质量。以往报道多以原儿茶醛或芍药苷等单一成分作为质控指标[2-3],本研究参考有关文献[4-8],对样品处理方法和色谱分离系统进行优化,采用高效液相色谱法(HPLC)同时对方中3味主药的特征性活性成分丹酚酸B、芍药苷、羟基红花黄色素A含量进行测定,从而在简化检测步骤、节约检测资源的情况下,更好地控制该药品的质量。
