Abstract: An analytical method for rapid determination of enrofloxacin, ciprofloxacin, ofloxacin, pefloxacin, norfloxacin, lomefloxacin and sarafloxacin in poultry eggs by QuEChERS and ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established. The quinolone residues in poultry eggs were extracted by 5% (V/V) formic acid-acetonitrile mixed solution, purified by QuEChERS and concentrated by a rapid solvent evaporation system, and separated on a C18 column with a mobile phase consisted of 0.1% (V/V) formic acid solution and acetonitrile by gradient elution. The quinolone residues were determined in a multiple reaction monitoring (MRM) mode by the electrospray ionization source (ESI+) and quantified with a matrix external standard method. The results showed that all the seven quinolones had good linearity in the concentration range of 2.0-100.0 ng/mL with the correlation coefficients greater than 0.995. The limits of detection (LOD) and limits of quantitation (LOQ) of the method were 0.3 μg/kg and 1.0 μg/kg, respectively, the average recovery rate was 77.20%-98.47%, and the relative standard deviation was 1.5%-6.2%. This method is easy, accurate and sensitive, which is suitable for rapid detection of quinolone residues in poultry eggs.
