    Abstract:
    A specific, sensitive and widely applicable high performance liquid chromatography with ultraviolet detection (HPLC-UV) method for the determination of moxifloxacin in human plasma was developed and validated in this study. The method involved a single step of liquid-liquid extraction with dichloromethane and the extraction yields more than 80% were achieved. The separation was performed on a common Kromasil C(8) column with an isocratic mobile phase. The total time was within 10 min per run. The calibration curve for moxifloxacin was linear in the concentration range of 0.05-5.0 μg/ml with correlation coefficient of 0.9997. The developed method was validated with excellent specificity, sensitivity, accuracy, precision and stability. Using this developed method, the pharmacokinetics of moxifloxacin in healthy Chinese volunteers was studied.
