| Sumario: | Tulathromycin is an approved antimicrobial used in cattle to treat respiratory diseases. An analytical\nmethod based on high performance liquid chromatography in tandem with electrospray ionization and\ndetection by mass / mass spectrometry (LC ESI MS / MS) was validated to quantify tulathromycin in different bovine tissues according to standards of National and International Regulatory Agencies. The optimized procedure involved homogenizing the sample with ethyl acetate and hydrochloric acid, hydrolysis of the resulting aqueous layer to convert tulathromycin and its metabolites into the marker residue (2R, 3S, 4R, 5R, 8R, 10R, 11R, 12S, 13S, 14R) -2-etil-3,4,10,13-tetrahidroxi-3, 5,8,10,12,14-hexametil-11 ? [[3,4,6-tridesoxi-3- (dimetilamino) -?-D-xilohexopiranosil] oxi] -1-oxa-6-azaciclopentadecan-15-ona, also known as CP-60,300, cleaning by using a cation exchange cartridge and subsequent analysis by LC ESI MS/MS. The proposed analytical methodology was validated meeting the acceptance criteria established by the reference organisms, proving to be adequate for the analysis of tulathromycin residues in bovine tissues for regulatory purposes.\n |
