咳喘宁颗粒质量标准研究

Study on Quality Standard for Kechuanning Keli Granule

目的：对咳喘宁颗粒进行质量标准研究。方法：采用薄层色谱法对咳喘宁颗粒进行定性鉴别；采用高效液相色谱法对咳喘宁颗粒中的盐酸麻黄碱进行含量测定。结果：盐酸麻黄碱的线性范围为0．668-4．008μg，平均回收率为100．83％。结论：此方法可行，重复性好，能有效地控制咳喘宁颗粒的质量。

Objective： To study the quality standard for Kechuanning Keli Granule. Methods.. Kechuanning Keli Granule was identified by TLC and Ephedrine Hydrochloride,in Kechuanning Keli Granule was determined by HPLC. Results： The linear relationship was at the range of 0. 668-4. 008μg for Ephedrine Hydrochloride. The average recovery was 100.83 % for Ephedrine Hydrochloride. Conclusion：The method is available with a good reproducibility and can control the quality of Kechuanning Keli Granule.
