The detection of prophylactic drugs in animal feeding stuffs by thin-layer chromatography

Abstract

A procedure is described for detecting the presence of seventeen prophylactic drugs commonly present in animal feeding stuffs. Only two solvent systems are used for separation purposes. The drugs investigated were: acinitrazole, 2-chloro-4-nitrobenzamide (aklomide), aminonitrothiazole, amprolium, N⁴-acetyl-4′-nitrosulphanilanilide (APNPS), buquinolate, decoquinate, dimetridazole, 3,5-dinitrobenzamide (DNBA), ethopabate, furazolidone, clopidol (metichlorpindol), nitrofurazone, pyrimethamine, methyl benzoquate, sulphaquinoxaline and 3,5-dinitro-o-toluamide (zoalene).
