外文摘要： 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)。
