Abstract
目的:建立六合散中磺胺嘧啶和乳酸依沙吖啶的含量测定方法.方法:采用HPLC法,岛津LC-10AT高效液相色谱仪;安捷伦TC-C18色谱柱;梯度洗脱,总流速为1.0 mg·mL-1;流动相A为乙腈,流动相B为0.5%乙酸铵溶液;检测波长:260 nm.结果:磺胺嘧啶在20.1~201.2 mg·mL-1范围内溶度和峰面积呈良好的线性关系(r=0.999,8),平均加样回收率为97.85%,RSD%为0.88%;乳酸依沙吖啶在3.36~33.60 mg·mL-1范围内溶度和峰面积呈良好的线性关系(r=0.999,9),平均加样回收率为97.87%,RSD%为1.01%.结论:该方法线性、精密度、重复性、稳定性、加样回收率良好,可用于六合散的质量控制.
