摘要：

Simple and sensitive methods have been developed for simultaneous detection of cyromazine melamine and their metabolites (ammeline ammelide and cyanuric acid) in samples of animal origins These include a high performance liquid chromatography (HPLC) method and a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method and are useful in regular monitoring and in toxicity studies of these molecules Representative samples used in this study include muscles and livers of swine bovine sheep and chicken kidneys of swine bovine and sheep and milk powder A new sample preparation procedure with pressurized liquid extraction (PLE) at 1400 psi and 70 C was investigated Quantification of these five compounds by HPLC was achieved using an APS-2 column with UV detection at 230 nm Limit of detection (LOD) was at 10 mu g kg(-1) and limit of quantification (LOQ) was at 40 mu g kg(-1) Recoveries of the five analytes in spiked samples ranged from 72 2% to 115 4% with RSD less than 12% Confirmatory analysis of the analytes was performed using LC-MS/MS in selected reaction monitoring (SRM) mode The LOD and LOQ were 5 mu g kg(-1) and 15 mu g kg(-1) respectively This is the first simultaneous analysis of cyromazine melamine ammeline ammelide and cyanuric and residues in complex tissue samples using PLE and HPLC It is expected that these methods will find many practical applications in evaluating the safety of cyromazine melamine and their metabolites (C) 2010 Elsevier B V All rights reserved
