Keyword:  精氨酸布洛芬注射液 高效液相色谱法 含量 有关物质;
Abstract: 目的采用HPLC法测定精氨酸布洛芬注射液的含量及有关物质。方法采用Waters C18色谱柱(150 mm×3.9 mm,5μm),流动相为水(磷酸调pH2.5)-乙腈(67∶34),检测波长214 nm,流速2.0 mL.min-1。结果布洛芬0.1~0.8 mg.mL-1与峰面积呈良好的线性关系(r=0.9986);最低检测限为28.2 ng;方法精密度RSD=0.63%(n=6);平均回收率为99.9%(n=9)。结论所用方法准确、灵敏、简便、快速,可用于精氨酸布洛芬注射液的含量及有关物质的测定。
