Abstract: 目的:研究盐酸索他洛尔片的质量标准及其稳定性.方法:样品用0.1mol/L盐酸溶解,经过滤后测定.紫外分光光度法的测定波长为228nm;高效液相色谱法采用ODS C18柱,以0.1%HAc-乙腈(80:20)为流动相,磺胺二甲基嘧啶为内标物,检测波长为228nm.结果:紫外分光光度法的线性范围为5~25mg/mL(r=0.9999),平均回收率为99.47%(n=9,RSD=0.87%);高效液相色谱法的线性范围为5~45mg/L(r=0.9997),平均回收率为99.01%(n=9,RSD=0.77%).结论:这两种方法用于测定盐酸索他洛尔片的含量考察稳定性具有准确、精密、简便的特点.
