摘    要:
目的建立高效液相色谱(HPLC)测定保健食品中违禁药品西地那非方法。方法采用C18柱,250mm×4.6mm×5μm;流动相:0.05mol/L磷酸三乙胺溶液(pH=3):甲醇:乙腈:58:25:17,在291nm波长处检测其含量。结果获得理想的分离效果,本方法最低检出浓度为0.18μg/ml,线性范围为0.584~292μg/ml,方法平均回收率为95.0%,RDS〈10%。结论该方法适用于保健食品中违禁药品西地那非含量的测定。

关 键 词:高效液相色谱法  保健食品  西地那非

Abstract:
Objective To determine sildenafil in health foods by high performance liquid chromatography (HPLC). Methods Sildenafil was detected on a C18 column (250 mm× 4. 6 mm × 5 μm) , mobile phase was a mixture of phosphate triethylaminc solution ( 0.05 mol/L, pH = 3 ) - methanol - acetonitrile ( 58 : 25 : 17 ) , wavelength was 291 nm. Results The detection limit was 0. 18μg/ml; linear range was from 0. 584 -292 μg/mL; the average recovery rate was 95.0% ; RSD was less than 10%. Conclusion The method refers to determination of sildenafil in health foods.
Keywords:High performance liquid chromatography  Health food  Sildenafil
