Abstract

Plants have been widely used throughout the world for their beneficial medicinal benefits. Passiflora edulis (passion fruit) belongs to the genus Passiflora, is widely distributed in sub-tropical and tropical regions around the world. The present study was evaluated to assess the antioxidant activities of Passiflora edulis leaves using three solvents – hexane, methanol and Aqueous. The antioxidant potential of Passiflora edulis leaves was determined by DPPH, ABTS and FRAP assay. Qualitative analysis of Passiflora edulis leaves confirms the presence of phytochemicals like steroids, alkaloids, flavonoids, tannins, polyphenols and terpenoids. The extracts of Passiflora edulis showed potent antioxidant activity in which methanol extract showed better radical scavenging activity with IC50 values of 26.23μg/mL DPPH assay and 20.27μg/mL for ABTS assay. Methanol extract of Passiflora edulis leaves has the highest FRAP value of 711.01μm/g indicating strongest antioxidant activity. Passiflora edulis can be considered as a potential source of natural antioxidant.
