[ Method] Coptis, Phelledendron, Pulsatilla and Astragalus in Compound Quanchangning Capsule were indentified qualitatively by thin layer chromatography ( TLC), and the content of berberine hydrochloride was determined by high performance liquid chromatography (HPLC), to study the quality standard of Compound Quanchangning Capsule. [ Result] TLC identification showed that the tested product was clear and well-separated with no interference. Berberine hydrechloride showed a good linear relationship with peak area at the injection volume of 10.92 - 163.74 ~Lg/mL, and the regression equation was Y = 39 611X -2 387. 9 (R2 = 0. 999 8) ; the average recovery was 97.60%, and the relative standard deviation was 1.64% (n =6). [ Conclusion] The standard is simple in operation and good in specificity, stability and repeatability, which is prompted as a favorable method for quality control of Compound Quanchangning Capsule.展开更多
目的建立复方青花颗粒的质量标准。方法采用薄层色谱法对金银花、甘草进行定性鉴别;采用高效液相色谱法测定绿原酸的含量,色谱柱为phenomenex Luna C18(5μm,250mm×4.6mm);甲醇-水-冰醋酸(20∶80∶1)为流动相,流速:1.0ml/min...目的建立复方青花颗粒的质量标准。方法采用薄层色谱法对金银花、甘草进行定性鉴别;采用高效液相色谱法测定绿原酸的含量,色谱柱为phenomenex Luna C18(5μm,250mm×4.6mm);甲醇-水-冰醋酸(20∶80∶1)为流动相,流速:1.0ml/min;检测波长:327nm。结果薄层色谱斑点清晰,分离效果好,阴性未见干扰;绿原酸在15.00-35.00μg/ml范围内呈良好的线性关系,r=0.9997(n=5),平均回收率为99.98%,RSD为1.13%(n=6)。结论本文所建立的方法操作简便、结果可靠、重复性好,可作为复方青花颗粒的质量控制标准。展开更多
