Detection method of cyantraniliprole and its metabolite j9z38 in pork

Abstract

The invention provides a detection method of cyantraniliprole and metabolite J9Z38 in pork. The detection method comprises the following steps: extracting, purifying, determining and carrying out fortified recovery test to obtain fortified recovery and relative standard deviation (RSDs) of the cyantraniliprole and the J9Z38; detecting minimum detectable amounts of the cyantraniliprole and the J9Z38; obtaining minimum test concentrations of the cyantraniliprole and the J9Z38 in the pork. According to the invention, an analytical detection method of the cyantraniliprole and the metabolite J9Z38thereof in the pork is established; by adopting acetonitrile to extract, and normal hexane to remove impurities of fat, protein and the like in the pork, a purifying and separating effect is good; themethod has the advantages of relatively simple pretreatment process, high recovery rate, high repeatability, good purifying and separating effect, relatively low minimum test concentration and suitability for analytical detection of the cyantraniliprole and the metabolite J9Z38 in the pork.

Description

technical field [0001] The invention relates to pesticide detection, in particular to a method for detecting cyantraniliprole and metabolite J9Z38 in pork. Background technique [0002] Cyantraniliprole (Cyantraniliprole) is another new anthranilamide insecticide developed by DuPont after chlorantraniliprole. It has the characteristics of high efficiency, low toxicity, novel mechanism of action, safety to non-target organisms, and no cross-resistance to existing insecticides. Cyantraniliprole has excellent control effect especially on piercing-sucking mouthparts pests, has broad application prospects, and has attracted widespread attention. [0003] The chemical name of cyantraniliprole is 3-bromo-1-(3-chloro-2-pyridyl)-N-{4-cyano-2-methyl-6-[(methylamino)carbonyl]phenyl }-1H-pyrazole-5-carboxamide; the chemical structure is [0004] [0005] Molecular formula C 19 h 14 BrClN 6 o 2 , molecular weight 473.7. Cyantraniliprole is a white powder with a melting point of...
