摘要
目的:建立HPLC法测定复方硫酸新霉素滴眼液中地塞米松磷酸钠的含量。方法:采用Eclipse XDB-C18色谱柱(250 mm×4.6mm,5μm),流动相为0.75%三乙胺溶液-甲醇-乙腈(40:55:5)流速1.0 ml·min-1,检测波长为242 nm。结果:地塞米松磷酸钠在0.1~1.21μg的范围内线性关系良好(r=0.999 8),平均回收率为99.0%,RSD为1.6%。结论:该法简便、快捷、准确,能更好的控制其质量。
Objective: To establish a HPLC method for Determination the content of Dexamethasone Sodium Phosphate in Compound Neomycin Sulfate Eye Drops. Method: Ecipse XDB-C18 column(250 mm×4.6 mm,5 μm)was used, 0. 75% Triethylamine solution-methanol-acetonitrile(40: 55:5 ) as mobile phase the flow rate was 1.0 ml·min^-1 and detection wavelength was 242 nm. Result: The linear range of Dexamethasone Sodium Phosphate was 0.1-1.21 μg( r = 0. 999 8 ,n = 5 ). The average recovery was 99.0% with RSD 1.6%. Conclusion: The method is simole, raoid and accurate. It can be used for aualitv control of this oreoaration.
