【摘要】:目的:建立同时测定复方氨酚烷胺片中对乙酰氨基酚、盐酸金刚烷胺、咖啡因、马来酸氯苯那敏含量的方法。方法:采用气相色谱法。色谱柱为HP-5石英毛细管柱,程序升温,检测器为氢火焰离子化检测器,检测器温度为300℃,载气为氮气,流速为1.5 m L/min,分流比为20∶1,进样量为1μL。结果:对乙酰氨基酚、盐酸金刚烷胺、咖啡因、马来酸氯苯那敏检测质量浓度线性范围分别为156.0~4 990.4、125.7~4 023.2、19.14~612.4、2.515~80.48μg/m L(r均为0.999 9);定量限分别为1.4、0.5、1.1、0.9ng,检测限分别为0.4、0.2、0.3、0.3 ng;精密度、稳定性、重复性试验的RSD2.0%;加样回收率分别为99.59%~101.77%(RSD=0.8%,n=9)、99.56%~101.80%(RSD=0.7%,n=9)、98.44%~100.83%(RSD=0.7%,n=9)、100.05%~101.91%(RSD=0.6%,n=9)。结论:该方法简便快速、准确可靠,适用于复方氨酚烷胺片中对乙酰氨基酚、盐酸金刚烷胺、咖啡因、马来酸氯苯那敏的同时测定。
