反相高效液相色谱法测定非洛地平缓释片的含量 |
[高血压医学论文]
【摘要】 目的:建立反相高效液相色谱法测定非洛地平缓释片含量的方法。方法:采用sinochrom-ODS-BP色谱柱(200 mm×4.6 mm,5 μm),以甲醇∶水(70∶30)为流动相,紫外检测波长240 nm,流速为1.2 mL/min,柱温为30 ℃。结果:本法在非洛地平浓度为5 μg/mL~50 μg/mL范围内线性关系良好,相关系数γ=0.9996,,日内精密度RSD≤1.7%。方法平均回收率为99.5%。结论:本法处理简便快速,测定准确、重现性好,适合于非洛地平缓释片质控中的含量测定。

Abstract Objective:A reversed phase HPLC method was developed to determine the contents of felodipine in felodipine sustained-release tablets.Methods:sinochrom ODS-BP column(200 mm×4.6 mm,5 μm)was used,and the mobile phase was composed of methanol-water(70∶30).The detection wavelength was at 240 nm with the flow rate at 1.2 mL/min,column temperature was controlled about 30 ℃.Results:The linear range was 5 μg/mL~50 μg/mL for felodipine(γ=0.9996),The average recoveries of felodipine were 99.5% ( RSD≤1.7%).Conclusion:This method appeared to be rapid,simple and accurate.
