3.2. DPPH Radical Scavenging Activity
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.
