Concentration dependant DPPH radical
scavenging ability of hydroethanolic extract
of M.calabura leaves.
Figure 3 demonstrates the DPPH scavenging ability of hydroethanolic extract of M.calabura leaves in a dose dependant manner.
The scavenging of the DPPH radical was in a concentration dependant manner with the IC50 value of 8.5 μg.
The strong inhibition of DPPH radical was recorded as 94.03 % at 40 μg concentration.
The scavenging ability of the plant extract attained saturation at the dose of 40 μg onwards.
It appears that hydroethanolic extract of M.calabura possesses hydrogendonating capability that confers antioxidant efficacy.
