Multiresidue Determination of Avermectins in Plant-Derived Food by UPLC-MS/MS

Abstract:

The objective of this study was to propose a method that the residues of avermectins (Abamectin, Emamectin Benzoate, Ivermectin, Eprinomectin and Doramectin) derived from the food plant were determined by UPLC-MS/MS. The avermectins were extracted with acetonitrile, purified by Alumina B or GCB/NH2 SPE cartridge, and then determined by ultra high-performance liquid chromatography with tandem mass spectrometry. Tests for recovery (Recovery rate: 80.6%～99.8%, RSD's: 0.22%～6.4%) were made by addition of avermectin standards at three different concentration levels (4, 20 and 100μg/kg) to five kinds of food plant as matrixes. The sensitivity, accuracy and precision of this method were able to meet the requirements for pesticide residue analysis.
