A method for simultaneous determination of oxytetracycline, tetracycline, chlortetracycline and choramphenicol in seafood was successfully developed using high performance liquid chromatography with ammonium acetate/water and acetonitrile as the mobile phase. The results showed that the four antibiotics were well separated under the optimum conditions, with the limits of detection being 32 μg/kg for oxytetracycline, 15 μg/kg for tetracycline, 23 μg/kg for chlortetracycline, and 19 μg/kg for choramphenicol. The recovery of standard additions was 76~92% and the relative standard deviation was 0.8-4.5%. The method is rapid, sensitive, accurate and reliable and can be applied in the analysis of antibiotic residues in seafood.
