Technical Abstract: More than 60% of peanut plant biomass remains after peanut pods are harvested. This biomass includes leaves, roots and testa. Freeze dried peanut plant leaves and roots, as well as oven blanched skins were analyzed for total phenolic compound concentation by the Folin Ciocalteu method and reported as feulic acid and gallic acid equivalents. The samples were also analyzed by ORAC and DPPH standard methods for antioxidant activity. Individual phenolic compounds separated by HPLC and identified by MS included catechin, epicatechin, ellagic acid, p-hydroxybenzoic acid and other hydroxylated compounds. These results indicate that the currently underutilized parts of the peanut plant may have nutraceutical properties.
