Abstract
目的:建立HPLC法同时测定扑麻滴鼻液中盐酸麻黄碱和马来酸氯苯那敏两组分含量的方法,提高质量控制标准.方法:采用HPLC法进行含量测定,色谱柱:Dikma Platisil ODS柱(250 mm×4.6 mm,5μm);流动相:乙腈-磷酸二氢铵缓冲溶液(20:80);流速:1.0 mL?min-1;柱温:35℃;检测波长:257 nm.结果:盐酸麻黄碱和马来酸氯苯那敏分别在207.38~622.13μg?mL-1(r=0.9999)、61.42~184.25μg?mL-1(r=0.9999)范围内线性关系良好;平均回收率分别为100.8%(RSD=0.91%)、99.4%(RSD=1.30%).结论:该方法简单准确、重复性好,可用于扑麻滴鼻液中盐酸麻黄碱和马来酸氯苯那敏的含量测定.
