A rapid and very effective analytical procedure for the simultaneous determination of four polyether antibiotics (PEs) lasalocid, monensin, salinomycin and narasin in poultry feeds was tested. PEs were extracted from samples using methanol and without any clean-up derivatized with 2,4-dinitrophenylhydrazine (DNP) in an acidic medium at 55 degrees C.
