In this study, we developed a new method to detect dinotefuran and its metabolites (UF and DN) in Oryza sativa (Rice) by HPLC-MS/MS in multiple reaction monitoring (MRM) modes. The recovery rates for dinotefuran, UF and DN were 82.3-85.8%, 83.7-89.0%, and 81.6-90.2%, respectively. The dissipation kinetics of dinotefuran in rice followed a combined first+first kinetic model, where the half-lives of dinotefuran and its metabolites were determined to be between 0.5 and 2.3days. The dinotefuran… CONTINUE READING
