摘要:目的:测定黄连药材及其炮制品中盐酸表小檗碱、盐酸黄连碱、盐酸巴马汀和盐酸小檗碱的含量,制定2010年版《中国药典》中黄连及其炮制品的质量标准。方法:以十八烷基硅烷键合硅胶为填充剂;流动相为乙腈-50mmol /L 磷酸二氢钾溶液(50ʒ50)(混合液中加15mmol /L 十二烷基硫酸钠,再以磷酸调节pH 为4.0);流速:0.6mL /min ;检测波长:345nm ;柱温:30ħ。结果:黄连药材中盐酸表小檗碱、盐酸黄连碱、盐酸巴马汀和盐酸小檗碱的含量分别不得少于0.93%、1.80%、1.45%、6.00%;黄连饮片、酒黄连、姜黄连和萸黄连中盐酸表小檗碱、盐酸黄连碱、盐酸巴马汀和盐酸小檗碱含量分别不得少于0.70%、1.50%、1.10%和5.00%。结论:该方法简便、灵敏、重现性好,适用于黄连及其炮制品质量品质的控制。中图分类号:R283

KEY WORDS :Rhizoma Coptidis ;HPLC ;epiberberine ;coptisine ;palmatine ;berberine

ABSTRACT :AIM :The contents of epiberberine hydrochloride ,coptisine hydrochloride ,palmatine hydrochlo-ride ,and berberine hydrochloride in the crude and processed Rhizoma Coptidis were determined to establish their quality standards for editing Chinese pharmacopoeia of 2010edition.METHODS :The C 18column was used ,the mobile phase was acetonitrile-50mmol /L monopotassium phosphate (50ʒ50)(containing 15mmol /L SDS and ad-justing pH =4.0with phosphoric acid )at the flow rate of 0.6mL /min ,the detective wavelength was set up at 345nm and the column temperature was 30ħ.RESULTS :The contents of epiberberine hydrochloride ,coptisine hydrochloride ,palmatine hydrochloride ,and berberine hydrochloride in Coptidis above 0.93%,1.80%,1.45%and 6.00%,respectively.The contents of epiberberine hydrochloride ,coptisine hydrochloride ,palmatine hydro-chloride ,and berberine hydrochloride in Rhizoma Coptidis decoctin pieces ,Rhizoma Coptidis processed with wine ,Rhizoma Coptidis processed with ginger and Rhizoma Coptidis processed with Fructus Evodia above 0.70%,1.50%,1.10%,5.00%,respectively were of the utmost importance.CONCLUSION :The method is simple and accurate ,and can be used to control the quality of the curde and processed Rhizoma Coptidis.
