| Abstract: | Objective To investigate the method and effect of reversed phase high-performance liquid chromatography （RP-HPLC） in the determination of human trimethoprim plasma concentration. Methods Agilent 1100 RP-HPLC instrument was selected to measure the concentration of human plasma trimethoprim. Results Trimethoprim linear equation Y = 6. 25 × 10 -4X ＋ 1. 08 × 10-2 ,the linear range was 0. 05 -10. 00 μg/ml. The relative standard deviation of trimethoprim intraday and interday precision （RSD） were 4. 4% and 4. 5% respectively,the recovery rate was 92. 1% ,the average concentration in the plasma was 0. 260μg/ml. Conclusion The method that determining human trimethoprim plasma concentration with RP-HPLC is simple,feasible,high sensitivity,and has good recovery,accuracy and precision. |
