Abstract: 目的建立高效液相色谱法测定注射用亚胺培南/西司他丁钠的含量及含量均匀度.方法采用CAPCELL PAK C18色谱柱(AQ型,250mm×4.6mm,5μm),流动相为含0.2%己烷磺酸钠的0.001mol/L磷酸二氢钾溶液(用0.5mol/L H3PO4调节pH6.8):甲醇(95:5),流速1.0ml/min,柱温50℃,检测波长254nm.结果亚胺培南的线性范围为0.120~0.600mg/ml(r=0.9995,n=5),西司他丁的线性范围为0.120~0.600mg/ml(r=0.9999,n=5),平均回收率分别为99.4%(RSD=0.6%),99.7%(RSD=1.0%).结论本法快速、准确、重现性好,能同时测定制剂中亚胺培南和西司他丁的含量与含量均匀度,还可用于控制该制剂的有关物质.
