A new liquid chromatography method has been developed and validated for the analysis of LI-S ((5R)-N-{[3-(3-fluoro-4 -morpholinylphenyl) -2-oxo-5-oxazolidynyl] methyl}acetamide)聽 (Fig.1) and its impurities L7 ((5R)-[3-(3-fluoro-4 -morpholinylphenyl) -2-oxo-5-oxazolidynyl] ...
The suggested method uses ODS column with methanol-phosphate buffer (pH 7) 6:4 as a mobile phase. The mean percentage recovery ranged from 97.4 to 98.8. The proposed method was applied to the determination of the selected drug in some pharmaceutical preparations. The statistical analysis of the...
RESULTS:The linear range of paeoniflorin was 0.100 1-2.502 8 μg;RSDs of precision,stability and reproducibility tests were lower than 2.0%,recovery rate was 98.7%-100.9%(RSD=0.86%,n=6). Reference substance amount,elution produce and the accuracy of method had great effect on the uncertain...
