TITLE:
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 mL/min,分流比为20 ∶ 1,进样量为1 μL。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、2.515~80.48 μg/mL(r均为0.999 9);定量限分别为1.4、0.5、1.1、0.9 ng,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RSD<2.0%;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。
ABSTRACT: OBJECTIVE: To establish a method for the simultaneous determination of paracetamol, amantadine hydrochloride, caffeine, chlorphenamine maleate in Compound paracetamol and amantadine hydrochloride tablet. METHODS: GC was performed on the column of HP-5 sillica capillary, temperature programmed, detector was FID detector, with the temperature of 300 ℃, carrier gas was nitrogen gas, the flow rate is 1.5 mL/min, the split ratio was 20 ∶ 1 and injection volume was 1 μL. RESULTS: The linear range was 156.0-4 990.4 μg/mL for paracetamol, 125.7-4 023.2 μg/mL for amantadine hydrochloride, 19.14-612.4 μg/mL for caffeine and 2.515-80.48 μg/mL for chlorphenamine maleate(all r=0.999 9); the limits of quantification were 1.4, 0.5, 1.1, 0.9 ng, limits of detection were 0.4, 0.2, 0.3, 0.3 ng; RSDs of precision, stability and reproducibility tests were lower than 2.0%; recoveries were 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) and 100.05%-101.91%(RSD=0.6%,n=9), respectively. CONCLUSIONS: This method is simple, rapid, accurate and reliable, and suitable for the simultaneous determination of paracetamol, amantadine hydrochloride, caffeine, chlorphenamine maleate in Compound paracetamol and amantadine hydrochloride tablet.
