"Determination Of Ionophores In The Tissues Of Food Animals By Liquid Chromatography"
Food Addit. Contam. 1995 Volume 12, Issue 6 Pages 731-737

Abstract: A liquid chromatographic method for determining residues of ionophores in bovine, porcine, and avian tissues is described. Tissues were extracted with iso-octane-ethyl acetate and the extracts purified on silica solid-phase extraction columns. Monensin, narasin and salinomycin were detected by UV absorbance following post-column derivatization with vanillin, and lasalocid was detected underivatized using fluorescence. In muscle, kidney and fat, all drugs were determined from a single sample extract. In liver, a separate extraction was done to determine lasalocid. The detection limit for lasalocid, narasin and salinomycin was 5 ppb; for monensin it was 2 ppb. Average recoveries were: lasalocid-71.0%; monensin-94.3%; salinomycin-97.2%; narasin-94.1%.
