Abstract
Plants are known as good sources of natural therapeutic agents.Plants generally contain secondary metabolites like phenolics, flavonoids, glycosides, coumarins, saponins, terpenoids and alkaloids etc. which reveal their specific characteristic properties and attribute to their pharmacological properties Bananas are popularly consumed fruits in world because of its simple taste, high nutritional value and potential health benefits. In the present investigation, different parts of two species of banana Musa acuminata cv. Grand Nain(flowers, root, bract, leaves) and Musa balbisiana (flowers, root, bract, leaves, seeds) were subjected to estimate total phenolic and flavonoid contents as well as extracts of these plant parts were also evaluated for their antioxidant activity by DPPH assay and peroxidase (POX) enzyme assay. Results of the present study indicated the presence of good quantity of total phenols and flavonoid contents in all the selected plant parts. The maximum phenolic content in Musa acuminate cv. Grand Nain was found in leaves (28.985±5.65 mg GAE/gdw) compared to flowers, Bract, and roots while flowers of the plant were found to possess the highest flavonoid content (64.87±9.62 mg QE/gdw) than other parts. In Musa balbisiana, flowers were found to have the maximum phenolic content (28.96±4.26 mgGAE/gdw) while, total flavonoid contents were found in leaves of the plant.The maximum free radical scavenging activity in Musa acuminate cv. Grand Nain was shown by roots with the lowest IC50 value (234.7±10.25 mg/L) while by bract in Musa balbisiana (234.65±12.58 mg/L).The maximum peroxidase activity was shown by acetone extract of roots of Musa acuminate cv. Grand Nain (0.412±0.034 mMole/min/g.dw). All experiments were done in triplicates. One way ANOVA analysis showed lack of significant differences in antioxidant activity and total phenolic and flavonoid contents among all the selected plant parts.
