[摘要] 目的 制订益母草颗粒制剂工艺和质量标准，提高质量的可控性。 方法 采用沸腾制粒技术制备颗粒，TLC鉴别益母草，紫外-可见分光光度法测定含量。 结果 改进了颗粒的制剂工艺，薄层色谱法鉴别明显，盐酸水苏碱线性回归方程为：Y = 0.605 6X - 0.003 1，r = 0.999 4，线性范围为0～8.153 6 mg，样品的平均回收率为98.5%(n = 9)，RSD = 1.03%，平均含量为21.5 mg/袋，含量限度为每袋中含有盐酸水苏碱不得低于18.0 mg。 结论 所建立的方法可准确地进行定性、定量检测，重复性好，可作为益母草颗粒的质量控制。

[Abstract] Objective To establish preparation process and quality standard for Motherwort Granules and improve the quality control. Methods The boiling pelletization techniques was used to prepare the nanoparticles. Motherwort was identified by TLC, Motherwort Granules was determined by UV-visible spectrophotometry. Results The results showed that, it improved the preparation process of Motherwort Granules, the spot of TLC was very clear, regression equation for Stachydrine Hydrochloride was Y = 0.605 6X-0.003 1, r = 0.999 4, Stachydrine Hydrochloride detected was stable during 0-8.153 6 mg, the average recovery of sample was 98.5% (n = 9), RSD = 1.03%, average concentration of samples was 21.5 mg/bag, limit for the content of each bag contained Stachydrine Hydrochloride not less than 18.0 mg. Conclusion The method is accurate and can be used for the quality control of Motherwort Granules.

益母草颗粒现收载于《中国药典》2010年版一部，为妇科经产之要药，主要用于经闭、痛经、产后瘀血、腹痛等妇科疾病[1]。现在市面上规格是每袋装15 g，由于服用量相对较大，辅料用量多，不利于患者的服用，颗粒干燥时间长，没有控制质量的指标性成分。为此，通过对制剂工艺进行改造，制剂规格由原来的每袋装15 g变更为每袋装5 g，每袋疗效不改变，辅料量减少了60%以上，有效地控制了成品的质量，方便了患者的使用，增强患者依从性，降低企业生产成本。
