摘要: A novel method for simultaneous detection of mycotoxins (e.g., aflatoxin B-1) or their metabolic residues in animal plasma with impurity adsorption purification followed ultra performance liquid chromatography. tandem mass spectrometry (UPLC-MS/MS) was developed. Extraction of mycotoxins and their metabolites from animal plasma sample was performed with 0.1% formic acid. acetonitrile solution after addition of sodium chloride and hydrous magnesium sulfate. The extract was then dehydrated and purified with hydrous magnesium sulfate, C-18, primary secondary amine, and alumina-A 3 mL of the supernatant was evaporated and re. dissolved with 0.5 mL of 0.1% formic acid aqueous solution/acetonitrile (70.30, V/V) for UPLC-MS/MS detection. The analytes were separated by a C-18 column utilizing gradient elution with 0. 1% formic acid aqueous solution containing 0.5 mmol of ammonium acetate and 0. 1% formic acid. methanol solution, and finally detected by tandem mass spectrometry in positive/negative ESI mode. Identification and quantification were achieved by LC-MS/MS with multi. reaction monitoring (MRM). Good linearity in response was obtained in the analytes concentration range of 0.05-100 ng/mL with correlation coefficients larger than 0.99. The limits of quantification (S/N = 10) were around 0.05-0.5 ng/mL. The recoveries of mycotoxins and their metabolites spiked in blank plasma samples were in the range of 62.0% - 116.4%, with relative standard deviations (RSDs) less than 19. 0%.
