Abstract:

Objective: To establish a method for determination of benzimidazoles residues in apples by UPLC-MS/MS. Methods: Sample was extracted with acetonitrile. After impurity removal by NaCl salting out, the sample was filtered through a membrane (0.2 μm), and injected into UPLC column. Identification was achieved by electrospray ionization in positive mode (ESI+) using multiple reaction monitoring (MRM). Results: The detection limits for carbendazim, thiabendazol, thiophanatemethyle were 0.17, 0.16, 0.07 μg/kg, respectively; the average recoveries for the three benzimidazoles in blank sample spiked at three levels (1.0, 5.0 and 10.0 μg/kg) were in the range of 89.2%-104.6%, and the RSDs were 1.7%-3.6% (n = 6). Conclusion: The method can completely meet the requirement of analysis for benzimidazoles residues in apples.
