optimization of sample preparation by central composite design for multi class determination of veterinary drugs in bovine muscle kidney and liver by ultra high performance liquid chromatographic tandem mass spectrometry
Food Chemistry, 2018Co-Authors: Tiele M Rizzetti, Maiara P De Souza, Osmar D Prestes, Martha B Adaime, Renato ZanellaAbstract:Abstract In this study a simple and fast multi-class method for the determination of veterinary drugs in bovine liver, kidney and muscle was developed. The method employed acetonitrile for extraction followed by clean-up with EMR-Lipid® sorbent and trichloracetic Acid. Tests indicated that the use of TCA was most effective when added in the final step of the clean-up procedure instead of during extraction. Different sorbents were tested and optimized using central composite design and the analytes determined by ultra-high-performance liquid chromatographic-tandem mass spectrometry (UHPLC-MS/MS). The method was validated according the European Commission Decision 2002/657 presenting satisfactory results for 69 veterinary drugs in bovine liver and 68 compounds in bovine muscle and kidney. The method was applied in real samples and in proficiency Tests and proved to be adequate for routine analysis. Residues of abamectin, doramectin, eprinomectin and ivermectin were found in samples of bovine muscle and only ivermectin in bovine liver.
