Abstract

An increasing demand for natural additives has shifted the attentionfrom synthetic to natural antioxidants. As vegetables are found to begood source of antioxidants and the present study is to examine thepotential & antimicrobial activity of extracts of leaves of Pimpenellatirupathansis with corns of Amorphophallus paeoniifolius.Antioxidant potential of leaves of Pimpenella & corns ofAmorphophallus were studied by using method like DPPH andreducing power. The aqueous extracts of Amorphophallus showedmaximum scavenging activity of DPPH followed by reducing powerrespectively when compared with Pimpenella & Amorphophallus.Total phenols were found to be 174 (Pimpenella) and 231.39(Amorphophallus) mg/g Gallic acid equivalent /g of dry material.These results suggest that phenolic and flavonoids in the leaves provedsubstantial antioxidant activity.

Keywords: Pimpenella tirupathansis, Amorphophallus paeoniifolius, Pimpenella & Amorphophallus.
