摘要
[ Objective] The research aimed to study the quality standard of Compound Quanchangning Capsule. [ 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.
