摘要

An HPLC/MS/MS method for the determination of arbidol in human plasma was developed. Arbidol and internal standard (loratadine) were extracted from alkaline plasma with tert-butyl methyl ether and analyzed on a Zorbax SB C18 column (30 x 2.1 mm id, 3.5 microm particle size). The detection was by monitoring arbidol at m/z 479.1 --> 434.1 and the internal standard at m/z 383.2 --> 337.2. The method was validated according to U.S. Food and Drug Administration guidelines. The calibration curve was linear over the range of 0.5-500 ng/mL using a 100 microL sample volume. The intraday and interday precisions were less than 6.5%, and acceptable values were obtained for accuracy, recovery, and sensitivity. The developed method was selective, simple, sensitive, and easily applicable.
