Abstract:Background: The objective of this study is to find out the antioxidant activity of plantain flower bract of Musa Paradisiaca. Musa paradisiaca is one of the most important fruit crops with some medicinal benefits which is beneficial to cure some diseases like diabetics, dysentery, ulcer etc. and it also have some antioxidant properties. Method: Oxidation is a process that produces free radicals which damage cells in human beings by inducing oxidative stress so that the antioxidant properties are used to remove or fight against the free radicals. The antioxidant activity was found out by DPPH (1, 1- diphenyl-2-picrylhydrazyl) free radical scavenging method and also, we have seen total antioxidant capacity assay. Results: Because this plantain flowers bract has high content of phenolic compounds and other phyto chemicals which contributes to the antioxidant activity. Conclusion: This DPPH free radical scavenging method was done by using methanol extract and the DPPH assay proved that the bract has potent antioxidant activity and it shows the 168.04 IC50 µg/ml for scavenging activity and 129.29 IC50 µg/ml for total antioxidant capacity assay.
