Simultaneous determination of vancomycin and norvancomycin in human plasma by LC-MS/MS
摘要
Abstract
Objective To develop an LC -MS/MS method for simulta-neous determination of vancomycin and norvancomycin concentrations in human plasma.Methods The plasma samples were precipitated by 25%trichloroacetic acid -acetonitrile ( 2∶1 ).The separation was a-chieved on ZORBAX Extend C 18 column with gradient elution using water and acetonitrile ( 0.1% formic acid in both ).Detection of the analytes were made using positive ion electrospray ionization ( ESI) in the multi-ple reaction monitoring ( MRM) mode.Results The linear calibration curves of vancomycin and norvancomycin were both in the range of 0.2-100.0 μg· mL-1 ( r=0.997 8 ) , with the lower limit of quantitation at 0.2 μg· mL-1.The average recovery was 94.4%-107.2%, Intra-day and inter-day relative standard deviations were both below 15%.Conclusion This method is rapid , sensitive , accurate , specific , and reliable, suitable for simultaneous determination of vancomycin and nor-vancomycin concentration in human plasma.关键词
