| Abstract: | Objective To make a c ontent determinatio nfor Levofloxacin mesylate inLevofloxacin mesylate for injection,in order to supervise its quality. Methods To assay by UV Spectrophotometry. Results The linear range of levofloxacin was 20. 2-1 79. 8 ug/ml （ r = 0. 9999 ）. The average recovery was 99. 43% with RSD 0. 77%. Conclusion UV Spectrophotometry is simple,rapid and accu r ate,it can be used as qualit y control of levofloxacin mesylate for injection. |
