The line chart shown in Figures 1(a)-(b) for DPPH radical scavenging potential of the ethanolic extracts of balbisiana and acuminata type of local varieties of banana peel respectively, elucidating the mean values
across the concentration range, clearly indicates the potential of Mondhan peel extract in scavenging free radicals as high percentage inhibition (98.19%) was noticed
at 10 mg·ml–1 in comparison to the peels of other varieties from both groups. DPPH radicals react with suitable
reducing agents, during which the electrons become
paired off and the solution loses colour stoichiometrically
depending on the number of electrons taken up [18]. In
the experiment, the solution progressively reduced to a
yellow coloured product, diphenylpicryl hydrazine, with
the addition of the extracts in a concentration-dependent
manner.
