摘要： The present study attempts to investigate a rapid, effective and sensitive analytical method to determine a new fungicide penflufen and its metabolite residues in potato, cowpea, corn, wheat and rice using ultra-performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS). The compounds were extracted using acetonitrile and cleaned up by primary secondary amine (PSA) and octadecylsilane (C18). Both compounds were determined in less than 5.0 min using an electrospray ionization source in positive mode (ESI+). The calculated limits of detection and quantification were below 0.018 mu g kg(-1) and 0.060 mu g kg(-1) in different matrices. The method revealed excellent linearity (R-2 > 0.9957) for both compounds. The recoveries ranged from 76.1 to 101.0% for both compounds with RSD values lower than 9.8% in all matrices. The results demonstrated that the method is reliable and effective enough for the routine detecting penflufen and its metabolite residues in vegetables and cereals. (C) 2016 Elsevier Ltd.
