ABSTRACT: Objective To establish a method for the rapid determination of 77 kinds of pesticide residues
in oil plants and plant oils by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/
MS). Methods Samples were extracted by QuEChERS with acetonitrile, and purified with PSA+C18 cartridge.
A gradient system of a mixture of 0.1% formic acid and acetonitrile with multi-reaction monitoring (MRM)
were adopted for quantitative determination. Results Seventy-seven kinds of pesti
