摘要
建立了HPLC法测定谷氨酸诺氟沙星注射液的有关物质及含量。采用ODS C18柱,以0.025mol·L^-1磷酸溶液(用三乙胺调节pH值至3.0)-乙腈(84:16)为流动相,检测波长为278m。谷氨酸诺氟沙星在18.8~93.9μg·mL^-1范围内线性关系良好(r=0.9998),检测限为0.505ng,平均回收率为99.80%,RSD为0.59%。
A HPLC method for determination of norfloxacin glutamate injection anct Its relatea substances was established. An ODS column was used with the mobile phase of 0. 025 mol · L^-1 phosphoric acid (pH 3.0, adjusted with triethylamine) -acetonitrile (84 : 16), the detection wavelength was 278 nm. The calibration curve was linear in the range of 18.8-93. 9μg · mL^-1 (r=0. 9998). The detection limit was 0. 298 ng. The average recovery was 99. 80%, with RSD of 0.59%.
