Pisonia grandis (R.Br) (grand devil's claw) (Nyctaginaceae) is a lettuce tree having anti-inflammatory, antidiabetic, diuretic, and wound healing activity. Antioxidant activity of aqueous fraction of ethanol extract of Pisonia grandis (R.Br) was analyzed by its electrochemical behavior. Cyclic voltammetry of the aqueous fraction of the ethanol extract at glassy carbon electrode with KCl as supporting 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 properties.

Abstract


Pisonia grandis (R.Br) (grand devil's claw) (Nyctaginaceae) is a lettuce tree having anti-inflammatory, antidiabetic, diuretic, and wound healing activity. Antioxidant activity of aqueous fraction of ethanol extract of Pisonia grandis (R.Br) was analyzed by its electrochemical behavior. Cyclic voltammetry of the aqueous fraction of the ethanol extract at glassy carbon electrode with KCl as supporting 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 properties.
