高效液相色谱法测定匹林咖敏片中3组分的含量
China Pharmacist(2009)
Abstract
目的:采用高效液相色谱法同时测定匹林咖敏片中3组分咖啡因、阿司匹林和马来酸氯苯那敏的含量。方法:色谱柱为ZORBAX Eclipse XDB-C_(18)(150mm×4.6mm,5μm),流动相为甲醇-4.3%冰醋酸溶液(17:83),柱温30℃,流速为1.0ml·min~(-1),检测波长为262nm。结果:咖啡因、阿司匹林和马来酸氯苯那敏的线性范围分别为:3.2~50.6μg·ml~(-1)(r=1.000 0)、24.5~392μg·ml~(-1)(r=1.000 0)和0.4~6.6μg·ml~(-1)(r=0.999 9);平均回收率分别为99.2%,99.3%,99.5%,RSD分别为1.1%,0.7%,0.6%。结论:方法快速、简便,适用于控制药品质量。
