摘要： We established an efficient analytical approach for simultaneous determination of benthiavalicarb-isopropyl and its four metabolites (KIF-230-M1, KIF-230-M3, KIF-230-M4, and KIF-230-M5) in fruits and vegetables. Samples were extracted with acidified acetonitrile, with octadecylsilane and graphitised carbon black as sorbent for clean-up, and UHPLC-MS/MS for determination. The approach was determined at spikes of 5, 50, and 500 mu g kg(-1). The recoveries of the six matrices analyzed ranged from 74.5% to 115.6% with 0.5-12.6% for intra-day RSDr (n = 5), and 0.4-13.8% for inter-day RSDR (n = 15). The five analytes in all matrices achieved high linearity (R-2 > 0.9917). The limit of quantification (LOQ) of benthiavalicarb-isopropyl as well as its four metabolites in all matrices was 5 mu g kg(-1). This analytical approach allows for monitoring residues of benthiavalicarb-isopropyl and its metabolites in vegetables and fruits.
