Abstract: | Summary A high-performance thin-layer chromatographic method based on solid-phase extraction has been developed for the qualitative
determination of seven quinolones (enrofloxacin, ciprofloxacin, danofloxacin, norfloxacin, flumequine, oxolinic acid and nalidixic
acid) in pork muscle. After preparation of the samples by extraction and clean-up by solid-phase extraction on reversed-phase
cartridges, extracts were spotted and eluted on silica gel plates. The plate is first inspected under UV illumination at 312
nm, then sprayed with terbium chloride solution and again monitored under 312 nm UV. The method has been validated to a level
of 15 μg kg−1 for enrofloxacin, ciprofloxacin, danofloxacin, norfloxacin and 5 μg kg−1 for flumequin, oxolinic acid and nalidixic acid. |
