Abstract：
:A micellar liquid chromatographic method was developed for the analysis of oxolinic acid, flumequine, marbofloxacin and enrofloxacin in honey. These quinolines are unethically used in beekeeping, and a zero-tolerance policy to antibiotic residues in honey has been stated by the European Union. The sample pretreatment was a 1:1 dilution with a 0.05M SDS at pH 3 solution, filtration and direct injection, thus avoiding extraction steps. The quinolones were eluted without interferences using mobile phase of 0.05M SDS/12.5% 1-propanol/0.5% triethylamine at pH 3, running at 1mL/min under isocratic room through a C18 column. The analytes were detected by fluorescence. The method was successfully validated according to the requirements of the European Union Decision 2002/657/EC in terms of: specificity, linearity (r(2)>0.995), limit of detection and decision limit (0.008-0.070mg/kg), lower limit of quantification (0.02-0.2mg/kg), detection capability (0.010-0.10mg/kg), recovery (82.1-110.0%), precision (<9.4%), matrix effects, robustness (<10.4%), and stability. The procedure was applied to several commercial honey supplied by a local supermarket, and the studied antibiotics were not detected. Therefore, the method was rapid, simple, safe, eco friendly, reliable and useful for the routine analysis of honey samples.
