摘要: 目的:建立氨咖黄敏胶囊中对氨基酚和对氯苯乙酰胺的HPLC测定方法。方法:色谱柱:Accerasil C8(4.6 mm×250 mm,5 μm);流动相:甲醇-磷酸盐缓冲液(磷酸氢二钠8.95 g,磷酸二氢钠3.9 g,加水溶解至1 000 mL,加10%四丁基氢氧化铵溶液12 mL),梯度洗脱;流速0.8 mL·min-1;检测波长为240 nm;柱温35 ℃;进样量20 μL。结果:对氨基酚浓度在0.100 5~30.15 μg·mL-1、对氯苯乙酰胺浓度在0.096 6~11.59 μg·mL-1范围内与峰面积线性关系良好(r≥0.999 7),检测限分别为0.17 ng、0.14 ng,平均回收率分别为101.60%、99.05%(RSD≤0.7% n=9)。结论:该方法专属性好、操作简便、快速准确, 可用于氨咖黄敏胶囊中对氨基酚和对氯苯乙酰胺的检测,可为提高该药的质量控制技术提供参考。

Abstract: Objective: To establish an HPLC method for determination of P-aminophenol and P-chloracetanilide in Paracetamol Caffein,Atificial Cow-bezaoar and chlorphenamine Maleate capsules. Methods: The eluate obtained was analyzed by HPLC method with Accerasil C8(4.6 mm×250 mm, 5 μm), phosphate buffer solution-methanol as a mobile phase gradient elution. The flow rate was 0.8 mL·min-1. The detection wave length was 240 nm,and the column temperature was 35 ℃. The injection volume was 20μL. Results: P-aminophenol and P-chloracetanilide showed good linearity in the ranges of 0.100 5~30.15、0.096 6~11.59 μg·mL-1 (r≥0.999 7) respectively. The detection limit were 0.17 ng、0.14 ng respectively. The average recovery values values of P-aminophenol and P-chloracetanilide of were 101.60%、99.05%(RSD≤0.7%, n=9) respectively. Conclusion: The method is simple with high accuracy and reproducible, which can be used for the determination P-aminophenol and P-chloracetanilide in Paracetamol Caffein, Atificial Cow-bezaoar and chlorphenamine Maleate capsules.
