【 摘 要 】

The objective ofthis research was to develop and validate an alternative analytical method forquantitative determination of levofloxacin in tablets and injection preparations.The calibration curves were linear over a concentration range from 3.0 to 8.0μgmL-1. The relative standard deviation was below 1.0% for both formulationsand average recovery was 101.42 ± 0.45% and 100.34 ± 0.85% fortablets and injection formulations, respectively. The limit of detection andlimit of quantitation were 0.08 and 0.25 μgmL-1, respectively. It was concluded that the developed method issuitable for the quality control of levofloxacin in pharmaceuticals formulations.
