Establishment of Analytical Method for Triforine Residue in Representative Crops Using QuEChERS and LC-MS/MS

摘要：

A precise single residue analytical method was developed for a fungicide triforine in various crops using LC-MS/MS. Apple, mandarin, Korean cabbage, green pepper, and brown rice were selected as representative crops, and clean-up system, partition solvent and extraction solvent were optimized. For LC-MS/MS, triforine was separated on UHPLC (Shimadzu UHPLC Nexera) with C18 column (Phenomenex Kinetex C18 100A 2.0 × 100 mm, 2. 6 μm) and gradient elution (0. 1％ formic acid and 0.1％ formic acid in acetonitrile, 0. 3 mL/min) , while Q1 , collision energy and Q3 were optimized for multiple reaction monitoring (MRM, 435 > 389.85, 98.15, and 214. 95 m/z) in MS/ MS (Shimadzu LCMS-8030).
