Abstract: A rapid HPLC method for simultaneous determination of abamectin and its toxicological metabolite in vegetables and fruits with fluorescent detector after pre-column derivatization was developed. After extracted by acetonitrile, overleaping cleaned-up step,the target compounds in samples was directly pre-column derivatised by TFAA-NMIM-CAN system. The results suggested that the fortified recovery and variation coefficient of added compouds in samples were 84.2%~110.8% and 1.9%~12.8%, respectively, the limited level of detection is 1μg·kg-1.

Key words: abamectin, derivatization, residue, HPLC, vegetable, fruit
