儿咳宁合剂质量标准研究

Quality Standard of Erkening Misture

目的：建立儿咳宁合剂的质量标准。方法：采用薄层色谱（TLC）法对方中莱菔子、浙贝母进行定性鉴别；采用高效液相色谱法测定制剂中黄芩苷的含量。结果：TLC中可清晰检出莱菔子、浙贝母；黄芩苷进样量在0．319-2．640μg范围内与峰面积积分值呈良好线性关系（r=0．9993）；平均回收率为99．56％，RSD=0．83％（n=9）。结论：所建标准可用于儿咳宁合剂的质量控制。

OBJECTIVE： To establish the quality stangard of Erkening misture. METHODS： Raphanus sativus and Fritillaria thunbergii were identifided by TLC, and the content of the Baicalin in Erkening misture was determinated by HPLC. RESULTS： The TLC spots of Raphanus sativus and Fritillaria thunbergii were distinctive. The linear range of Baicalin was 0. 319--2.64μg （r = 0. 999 3） . The average recovery was 99. 5696, and RSD was 0.83% （n = 9） . CONCLUSION： This established standard can be used for the quality control of the Erkening misture.
