A high-performance liquid chromatography with ultraviolet spectrophotometer detection method for the simultaneous determination of oxytetracycline (OTC), tetracycline (TC), chlortetracycline (CTC), and doxycycline (DC) residues in chicken liver was developed and validated. Chicken liver was digested using perchloric acid of 5% mass concentration. The chromatographic separation was performed on an Agilent column. Matrix matched calibration curves showed a linearity exceeding 0.9985. The accuracy values lay between 71.7% and 87.3% and the coefficient variation was lower than 17.3%. Limits of detection and quantitation were below 0.03 μ g /kg and 0.09 μ g/kg, respectively, for CTC, OTC and DC. The method was employed to analyze chicken liver from the food market. Residues were detected to be 1-4μg mL^-1 for CTC, TC and OTC, and no DC was detected. The experiments demonstrated that the process is simple and stable with the accuracy and sensitivity meeting the requirement of residual analysis, and thus it is suitable for detection of residual TCs in chicken liver.
