Abstract: | Electrochemical reduction behavior of 3-acetoxyflavone was compared with 3-hydroxyflavone on glassy carbon electrode with
DMF and 60% DMF/Britton Robinson buffer at pH 3.8 & 10.1 using cyclic voltammetry (CV) and on dme using normal pulse polarography
(NPP). Single irreversible reduction waves were observed due to the reduction of keto moiety. The effects of change in medium,
pH and sweep rate were evaluated. The electrode process was found to be diffusion controlled and enhanced substituent effect
was noticed due to extended conjugation. Kinetic parameters were calculated from CV & NPP measurements using R.S. Nicholson
and I. Shain equation and Meites & Isreal equation, respectively.
