摘要: 目的 :建立泻痢停的含量测定方法。 方法 :应用计算机辅助褶合曲线分析法结合计算机信息处理技术,不经分离直接测定磺胺甲噁唑和甲氧苄氨嘧啶的含量。 结果 :磺胺甲噁唑在0-20μg/mL范围内线性良好,回收率为99.85%,相对标准偏差为0.53%;甲氧苄氨嘧啶在0~12μg/mL范围内线性良好,回收率为 102.01%,相对标准偏差为3.14%。 结论 :该法简便、快速,结果可靠,重现性好。Abstract: Objective : To establish a method for determination of contents in Xieliting tablets. Methods : The computer-aided con-juction curve method had been applied to determine sulfamethoxazol and trimethoprim. Results : The corresponding average recovery and the relative standard deviation of sulfamethoxazol and trimethoprim were 99.85% ,0.53% , 102.01% ,3.14% ,the linear range of sultamethoxazol and trimethoprim were 0-20μg/mL,0-12μg/mL. Conclusions : The method was satisfactory, simple and convenient and had a good accuracy.
