ResumoA high-performance liquid chromatographic method for the determination of lomefloxacin in human plasma has been developed and validated. A solid-phase extraction procedure was used to isolate lomefloxacin from the biological matrix prior to the quantitative analysis. The compound was separated on a Vydac anion-exchange column using acetonitrile—phosphate buffer (pH 7.0) as the mobile phase and quantified by measuring its UV absorbance at 280 nm. The lower limit of detection for the analyte was 0.05 μg ml−1. Enoxacin was used as the internal standard. The calibration graph of the method was linear from 0.1 to 10 μg ml−1 of lomefloxacin in human plasma. This procedure is suitable for pharmacological and pharmacokinetic studies of lomefloxacin.
