摘要：

A method for the determination of bisultap in tropical fruits was developed by modified QuEChERS method and ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The tropical fruit samples were twice extracted with acetonitrile containing 1% (v/v) acetic acid, and purified by 200 mg of primary secondary amine (PSA), 100 mg of C18, 300 mg of MgSO4 and 500 mg of disodium hydrogen citrate. The analyte was separated on a CAPCELL CORE PC hydrophilic column, detected in the negative ion multiple reaction monitoring (MRM) mode, and quantified by external standard method. A good linear relationship in the range of 0.1-10.0 mu g/L was obtained with the correlation coefficient (r(2)) of 0.999 3. The limit of detection and limit of quantification were 0.015 g/kg and 0.05 g/kg, respectively. The spiked recoveries were in the range of 81.0%-88.3% with the relative standard deviations from 3.9% to 6.2%. The method has good purification effect and high sensitivity, and is suitable for the rapid analysis of the bisultap residues in tropical fruits.
