Abstract

Elecrrochemtcal reduction behavior of 7-acetoxyJlavone was compared .with 7-hydroxyfavone on glassy carbon electrode with DMF and 60% DMF/Britton Robinson bufler at pH 3.8 & 10.1 using cyclic voltammetty. Single irreversible reduction waves were observed due to the reduction of keto moiety. The eflects of change in medium, pH and sweep rate were evaluated The electrode process was found to be d~flusion controlled and enhanced substituent eflect was noticed due to extended conjugation. Kinetic parameters were calculated fram cyclic voltammetric measurements using R.S.Nicholson and IShain's equation.
