Fruits are considered to be rich in antioxidants but the total antioxidant potential is yet to be unveiled systematically in case of wild edible fruits. The present paper attempts to focus on assessing the levels of enzymatic activity of Superoxide dismutase (SOD), Catalase and Peroxidase enzymes in selected eight wild edible fruit species of Odisha viz. Aegle marmelos, Calamus guruba, Limonia acidissima, Phyllanthus acidus, Phyllanthus emblica, Syzigium cumini, Ziziphus mauritiana and Ziziphus oenoplia. As per the results inferred, SOD enzyme activity of Phyllanthus acidus (2.66 ∆OD-1.min-1.mg-1 protein) was found to be the highest and almost equal to Ziziphus oenoplia (2.15 ∆OD-1.min-1.mg-1 protein). Catalase enzyme activity was found to be very high in Calamus guruba (4.2 × 104 I.E.U.) followed by Phyllanthus acidus (4.08 x 104 I.E.U.), Aegle marmelos (3.77 × 104 I.E.U.) and Syzigium cumini (3.65 × 104 I.E.U.). Peroxidase enzyme activity was highest in Calamus guruba (0.975 OD-1.min-1.gm-1 tissue wt.) and at par with Aegle marmelos (0.645 OD-1.min-1.gm-1 tissue wt.). From this study, it could be concluded that wild edible fruits like Aegle marmelos, Calamus guruba, Phyllanthus acidus, Syzigium cumini and Ziziphus oenoplia can be identified as beneficial fruit species that possess significant free radical scavenging levels. Exploration and higher intake of such fruits with functional attributes could impart promising therapeutic potential.
