摘      要：Five thyreostats(TSs),namely tapazole,thiouracil,methylthiouracil,propylthiouracil,and phenylthiouracil,were determined in bovine urine using ultra-high performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS)in positive electrospray ionization *** and clean-up were achieved using a ChemElut cartridge with tert-butyl methyl ether,without a derivatization *** was achieved on an Acquity UPLC SS T3 *** mobile phase was acetonitrile and water containing 0.2%(v/v)formic *** mass spectrometer was operated in multiple reaction monitoring *** samples were spiked with TS solution at levels corresponding to 5,10,15,and 20μg/*** accuracy(internal standard corrected)ranged from 92%to 107%,with a repeatability precision(relative standard deviation,RSD)less than 15%for all five *** RSDs within-laboratory reproducibility was less than 26%.The decision limits(CCα)and detection capabilities(CCβ)were obtained from a calibration curve and were in the ranges of 3.1-6.1μg/L and 4.0-7.4μg/L,*** CCαand CCβvalues were below the recommended concentration,which was set at 10μg/*** results show that the described method is suitable for the direct detection of TSs in bovine *** method can also be used to determine TSs in porcine urine.
