Abstract: A high-performance liquid chromatography (HPLC) method was established for detecting residues offourfluoroquinolones in black-boned chicken.Thechicken samples were minced,homogenized,andextracted using a phosphate bufer solution,followed by purification with solid-phase extraction columns.The analytes were then quantified via HPLC.Results showed that under optimal experimental conditions,the linear relationships for ciprofloxacin,danofloxacin,enrofloxacin,andsarafloxacin were excellent,with correlation coficients R2 ) exceeding 0.999. The method demonstrated detection limits of 0.474 6μg?kg-1 to 4.849μg?kg-1 and quantification limits of 0.943 6μg?kg-1 to 10.070μg?kg-1 for the four target analytes. At three spiked concentration levels, the average recoveries of the four fluoroquinolones ranged from 80.38% to 101.70% ,with relative standard deviations between 0.46% to 1.52% .These findings indicate that the method is accurate,sensitive,and reliable,meeting the requirements for veterinary drug residue analysis.It provides a technical reference for detecting restricted and banned fluoroquinolones in animal-derived food products at the grassroots level.
