Hydrogen peroxide is scavenged via its reduction product the hydroxyl radical (OH•) and the loss of hydrogen peroxide can be measured spectrophotometrically at 230 nm. The percentage inhibition of the hydrogen peroxide radical increased with increasing concentrations of alcoholic extract, aqueous extract and ascorbic acid. The IC50 value was found to be lowest for ascorbic acid (55 μg/ml) followed by the alcoholic extract (91 μg/ml) and aqueous extract (180 μg/ml). The lower the IC50 value, the higher the inhibitory activity.
