Abstract:
Objective:To establish a method for the determination of nimesulide granules by HPLC. Methods:An Inertsil ODS-SP C18 column(250 mm × 4. 6 mm,5 μm) was used, and the mobile phase was 0. 01 mol·L-1 potassium hydrogen phosphate anhy-drous-acetonitrile(55∶45)[adjusting pH to (7. 2 ± 0. 05) with phosphoric acid]. The detection wavelength was set at 399nm and the flow rate was 1.0 ml·min-1. The injection volume was 20 μl. Results: The linear range of nimesulide was 0.044-0.222 μg(r=0. 999 9), the average recovery was 99. 22% and RSD was 0. 46%(n=6). Conclusion:The method is simple, accurate with promis-ing sensitivity and reproducibility, and can be used in the determination of nimesulide granules .
