Abstract
Pisonia grandis (R-Br) (grand |devil’s claw) Qfyctaginaceae) is a lettuce tree having anti-inflanunatoiy, antidiabetic,
diuretic, and wound healing activity. Antioxidant activity of aqueous fraction of ethanol extract o f Pisonia grandis
(R.Br) was analyzed by its electrochemical bdiavior. Cyclic voltammetry o f the aqueous fraction o f the ethanol extract
at glassy carbon elec tive with KCl as su j^ rtin g electrolyte revealed a reversible and an irreversible redox reaction
which is due to the presence of one or more secondary metabolites like flavonoids, phenols and tri-terpenoids having
antioxidant propoties
