3.5. Total Phenol and Flavonoid Content
The total phenol and flavonoid content of the different
banana peel extracts is shown in Table 2.
The antioxidant activity of the plant products is associated to their bioactive compounds, mainly antioxidant
phenolics, because of their ability to scavenge free radicals [22,23]. Phenols are secondary metabolites in plants
and are known to possess a wide range of therapeutic
uses, such as antioxidant, antimutagenic, anticarcinogenic,
free radical-scavenging activities and also decrease cardiovascular complications [24]. From the results, it is
inferred that Rasthali extract showed higher phenol content compared to other varieties, which could be related
to its antioxidant potential.
Many flavonoids are found to be strong antioxidants
capable of effectively scavenging the reactive oxygen
species because of their phenolic hydroxyl groups [25].
In our study, from the table values, Poovan peel extract
exhibited higher flavonoid content which might be correlated with its anti-lipid peroxidation activity.
Several mechanisms have been proposed to be involved in the antioxidant activity such as hydrogen donation, termination of free radical mediated chain reaction,
prevention of hydrogen abstraction, chelation of catalytic
ions, and elimination of peroxides [26].
Antioxidant activity is a dependent system and the
characteristic of a particular system can influence the
outcome of the analysis. Hence, a single assay would not
be representative of the antioxidant potential of plant
extracts. In the present study, we employed different
models of antioxidant assays which could provide a more
reliable approach to assess the antioxidant and radical
scavenging potential of peel extracts of various banana
varieties.
4. Conclusions
The investigation of the antioxidant potential and phytochemical content of banana peel of nine different local
varieties showed that the content of total phenols were
higher in Rasthali compared to other species which might
be correlated with its high ABTS scavenging activity. In
contrast, the content of flavonoids was higher in Poovan
banana and is highly correlated with its lipid peroxidation inhibition activity. Hence the relationship between
phytochemical content and free radical scavenging activity of banana peel indicates that peel extracts from these
varieties may be useful to combat free radical mediated
diseases. These observations may be used to substantiate
