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. |
