摘要
用多波长数据线性回归法和正交函数分光光度法,不经分离直接测定复方新诺明片中磺胺甲基异恶唑(SMZ)和甲氧苄氨嘧啶(TMP)的含量。本法方法简单,操作迅速。磺胺甲基异恶唑的平均回收率为99.72—100.5％,变异系数小于0.48％,甲氧苄氨嘧啶的平均回收率为99.25—99.46％,变异系数小于0.83％。其准确度和精密度能满足制剂分析的要求。
The linear regression method of multiwavelength data and orthogonal functions spectropho-tomtry have been used for the determination of sulfamethoxazole and triemethoprim in co-trimo-xazole tablets without any preliminary separation.The methods are simple and rapid.Good results have been obtained. The average recovery of sulfamethoxazole was 99.72-100.5%, with coefficient of variation below 0.48%, and the average recovery of triemethoprim was 99.26-99.46%, with coefficient of variation below 0.83%. The accuracy and precision meet the requirements of analysis of the pharmaceutical preparations
