Abstract

Antioxidant potential of some lesser known wild edible fruits of Odisha

Jyotimayee Nayak and Uday Chand Basak

Wild edible fruits can be considered as nutraceuticals as they provide a wide range of necessary supplement including a variety of antioxidant compounds apart from its nutritional value. Though not so popular, wild fruits like Antidesma acidum, Artocarpus lacucha, Bridelia retusa, Carmona retusa, Carissa spinarum, Melastoma malabathricum and Streblus asper are mainly consumed by tribal, forest dwellers and rural people of Odisha. Inspite of their several nutritional and medicinal properties, adequate literature and scientific evidences regarding their importance is still lacking. Hence this study has been undertaken to determine antioxidant potentials in above mentioned wild fruits. Amongst all the fruits analyzed, fruits of Melastoma malabathricum was found to possess highest total antioxidant activity (FRAP) 5878.35±0.05 μM AEAC /g dry wt. and total phenolic content 1.92 g GAE/100 g whereas Carissa spinarum recorded best DPPH activity (1013 mg AEAC/100g dry wt.) and highest carotenoid content 72.19 mg/100g. Carmona retusa possessed highest ascorbic acid content (285.71 mg/100g). In case of antioxidant enzymatic assays, Melastoma malabathricum yielded highest peroxidase activity i.e. 0.1 Δ O.D / min / g fwt. while Bridelia retusa possessed highest catalase activity (3.5702 ± 0.011 U/ml). In case of Superoxide Dismutase enzyme assay Antidesma acidum showed highest activity (0.916 Δ O.D / min / g tissue wt.). From all the given experimental data, it can be appraised that Melastoma malabathricum, Carissa spinarum, Carmona retusa and were the most promising fruits and these fruits required to be popularized as nutraceuticals.
