摘要:

采用高效液相色谱法测定乙烷硒啉注射剂中乙烷硒啉的含量。使用ODS色谱柱, 流动相组成0.01%磷酸-甲醇 (60:40, v/v), 流速1.0 mL/min, 柱温40 °C, 检测波长320 nm, 进样体积20 µL。结果表明: 在上述色谱条件下乙烷硒啉色谱峰峰型良好, 在10-50 µg/mL浓度范围内, 乙烷硒啉浓度与峰面积之间线性良好 (r2 = 0.9999), 最低检测限为100 ng/mL, 精密度、日间与日内差、稳定性、回收率均符合要求。自制三批乙烷硒啉注射剂的含量以标示量计, 在102%-103%之间。本法简单、准确、可靠, 可用于乙烷硒啉注射剂含量的测定。

Abstract:

A novel ethaselen injection formulation has been developed in our laboratory. The objective of the present study was to establish and validate a high performance liquid chromatography (HPLC) method for the determination of ethaselen in its injection formulation. Analysis was performed on an ODS column with isocratic elution at 40 °C. Mobile phase was consisted of 0.01% phosphoric acid and methanol (60:40, v/v). The detection wavelength was set at 320 nm and the flow rate was 1.0 mL/min. The results showed that the calibration curves of ethaselen were linear in the range of 10-50 µg/mL (r2 = 0.9999). The limit of detection for ethaselen was 100 ng/mL. The average recovery of ethaselen was 100.14%. The labeled content of ethaselen in its injection formulation was in the range of 102%-103% of the measured content. In conclusion, this method was stable and reproducible, thus providing a useful tool for the routine analysis of this novel ethaselen injection formulation.
