ABSTRACT: The study has been aimed to evaluate and compare phytochemical content and the antioxidant activity in peel extracts of nine local varieties of banana, i.e. Musa sapientum species. Ethanolic extract of peels of these varieties were subjected to in vitro free radical scavenging assays like DPPH, ABTS and lipid peroxidation inhibition assay. Total antioxidant capacity assay to confirm the antioxidant potential and phytochemical content such as total phenols, flavonoids were also determined. The results obtained were analyzed statistically by ANOVA and DMRT analysis. The peel ex- tracts of all the nine varieties of banana exhibited significant antioxidant and phytochemical activities with Musa spp – Blueggoe (Monthan) - AAB and Musa spp – Rasthali – AAB showing highest free radical scavenging activity and Musa spp – Karpooravalli – ABB, Musa spp – Rasthali – AAB, Musa spp - Ney Poovan (Kadali) – AB and Musa spp – Mysore (Poovan) – AAB having highest phytochemical content. The study suggests that peel extracts of these banana varieties could be useful to combat free radical mediated diseases.
