A rapid method for the determination of residues of chloramphenicol in tilapia by ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established. The samples were extracted with acetonitrile, and separated on a C18 column using methanol-water solution as mobile phase, and then detected under ESI- multiple reaction monitoring mode. The method showed a good linearity for the analysts over the range of 0.1-100μg/L. The detection limits were 0.10μg/kg. The recoveries ranged from 88.6% to 108% at spiked concentrations with the relative standard deviations lower than 5%. The results shows that this method has the advantages of easy to operate, fast to perform, with high sensitivity and accuracy, and it is suitable for detection of residues of chloramphenicol in tilapia.
