In this investigation electrochemical behavior ofmonalide is studied and its residues in vegetable samples is determined by using deferential pulse polar graphic method. In this investigation dropping mercury electrode is used as working electrode and universal buffer with pH range 4.0-6.0 is used as supporting electrolyte. Investigated compound was found to exhibit well resolved peak at pH 4.0. Peak currents were linear over the concentration range of 1.0x 10-5Mto 1.0x10-10Mwith lower detection limit of 1.09x 10-9 M. The relative standard deviation and correlation coefficients were found to be 1.25%, 0.996 respectively for 10 replicates.
