摘要: In this study, a multi-residue determination method of QuECHERS combined with UHPLC-MS/MS was developed to determine nine P-lactam antibiotics (penicillin G, amoxicillin, ampicillin, cephalexin, cefquinome, ceftiofur, cefazolin, cephapirin, cefuroxime) in aquaculture products. All the nine P-lactam antibiotics exhibited excellent linearity within the range of 2.0 & ndash; 200 ng/mL (cefuroxime: 5.0 & ndash;200 ng/mL, r greater than 0.999), while the limits of detection (LODs) and quantification (LOQs) were 2.0 & ndash;5.0 & micro;g/kg and 5.0 & ndash;10.0 & micro;g/kg, respectively. The recoveries of this method in five aquaculture products (Penaeus Orientalis, Cyprinus Carpio, Channa Argus, Aristichthys Nobilis, and Ctenopharyngodon Idella) ranged from 85.4% to 113.3% and the intra-day and inter-day precisions (%RSDs) were less than 15%. The results suggested the feasibility of this method as a rapid, simple, and accurate approach for determining the residues of the P-lactam antibiotics in aquaculture products.
