Abstract:

Quinolones (QNs) is one kind of antibiotics, and in recent years its residue exceeding limits has been found frequently n animal-origin exportation food such as bee products. In this study, liquid-liquid extraction was used to pre-treat royal jelly ample, and then five QNs residues in royal jelly sample were determined by high-performance liquid chromatography coupled ith fluorescence detector. The results showed that the detection limits of ofloxacin, enrofloxacin, ciprofloxacin, norfloxacin and anofloxacin are 5 μg/kg, 2.5 μg/kg, 2.5 μg/kg, 2.5 μg/kg and 1 μg/kg, respectively, which meet the detection demand of allowable imits of QNs in royal jelly. The proposed method is simple, rapid, accurate and low-reagent consumption and cost.

Key words: high-performance liquid chromatography coupled with fluorescence detector, oyal jelly, quinolones, residue
