Abstract: A method for the determination of phoxim in garlic was established with HPLC. Residues of phoxim were extracted from sample with acetonitrile.Chromatography was performed on a RP-C18 column with DAD detector and the external standard method was used.The detection limit of phoxim is 0.02mg/kg in the garlic sample and the recoveries are greater than 76%, RSD was less than 4%.
