【摘要】 目的:采用 HPLC 法测定盐酸头孢他美酯原料药及其片剂的含量。方法:以 Nova-PakC₁₈为色谱柱,乙睛-甲醇-水-磷酸盐缓冲液（360:95:500:45）流动相,检测波长为263nm。结果:线性关系 r=0.9999,平均回收率为99.94%,RSD=0.44%（n=5）。结论:方法简便、准确,适用于该产品的质量检验分析。更多还原

【Abstract】 Objective:Cefetamet pivoxil hydrochloride and its tablets were determined by a new HPLC method.Method:The separation was performed on a Nova-Pak C₁₈ Column.The mo- bile phase was composed of acetonitrile-methanol-water-phosphate buffer（360:95:500:45）. The UV detector was set at 263 nm Results:The average recovery was 99.94%（RSD=0.44%,n =5）with good linear relationship （r=0.9999）.Conclusion:The method was simple and accurate and can be used for the quality control of cefetamet pivoxil hydrochloride and its tablets.更多还原
