Abstract: A method to determine thiacloprid residue in vegetables was developed using high performance liquid chromatography with diode array detector (HPLC-DAD). Samples were extracted by acetonitrile, cleaned up on florisil SPE column, separated on C8 liquid chromatography columns and detected with DAD. The average recoveries of thiacloprid in three species of vegetables at three spike levels were 81.8%-97.5% with a relative standard deviation of 1.36%-7.80% (n = 6). The detection limit of the method was 0.02 mg/kg.

Key words: vegetables, thiacloprid, residue, high performance liquid chromatography, DAD
