Abstract
In this study a comparative analyses on phytochemical and antioxidant properties of two varieties of Musa sp. L. was conducted. The varieties selected were: variety 1 Nendran and variety 2 Kunnan. Flowers, bracts and peel of unripened fruits of two banana varieties were dried and ground into powder form and extracts were prepared using water and ethanol. Extracts were screened for the phytochemicals both qualitatively and quantitatively. The antioxidant activity of different ethanol extracts were estimated using the DPPH radical scavenging protocol. The results showed the presence of carbohydrate, sugar, proteins, ketose, quinone, cardiac glycoside, terpenoids, flavanoids, phenols and saponins in the extracts of flower, spathe and peel in both the varieties studied. Quantitative estimation of metabolites revealed greater amount of primary metabolites in Kunnan and secondary metabolites in Nendran banana respectively. More antioxidant activity was exhibited by the extracts of Nendran than Kunnan variety.
