The use of veterinary medicines may be cause of the presence of drug residues in animal food products if appropriate withdrawal periods are not respected or if contaminated feeds are used. This work presents the development of an HPLC-FLD method for the quantitative de-tection of eight quinolones – norfloxacin, ciprofloxacin, danofloxacin, enrofloxacin, difloxacin, oxolinic acid, nalidixic acid, flumequine– in bovine milk. After deproteination and extraction with a metaphos-phoric acid 1% w/v / methanol / acetonitrile (60/20/20 v/v/v) solution, the sample is partially evaporated and cleaned up on a reversed phase SPE cartridge.The extract is analyzed using an high performance liquid chromatograph with fluorescence detector. Mean recovery ranged between 65% - 88%. All the an-alytes can be identified and quantified in the concentration range 15 - 60 μg/Kg for danofloxacin and 25 - 150 μg/Kg for the other quinolones.}, number={5}, journal={Italian Journal of Food Safety}, author={Gili, Marilena and Marchis, Daniela and Stella, Paola and Olivo, Fabio and Ostorero, Federica and Franzoni, Mauro and Abete, Maria Cesarina}, year={2012}, month={Oct.}, pages={35–38} }
