In Vitro Antioxidant Activity Of Ethylene Acetate Of Sundried Orange Peel.

ABSTRACT

The oranges were purchased from the local market of Nndoru. The orange peels were Sundried (55 °C) and subsequently subjected to extraction with Ethiacetate. The Phenolic content of the sample was studied according to the method described by Folic-Ciocalteu. Whereas the total Flavonoid content was studied according to the aluminium chloride method. Invitro antioxidant activity of the sundried peel were assessed using three different methods (DPPH) (1,1 -diphenyl-2- picrylhhydrazl) scavenging activity, Reducing power and Hydrogen peroxide percentage inhibition). The in-Vitro antioxidant activity on the sample was evaluated, while the antioxidant activity by Reducing power in the sundried peel was low and higher in the ascorbic acid (Standard antioxidant). The DPPH radical, scavenging ability, reducing power and hydrogen peroxide inhibition of the extract was found to increase with increasing extract concentration.
