Most of the tannins, flavanoids and phenolic compounds may be responsible for antioxidants
properties of many plants (Larson, 1988). In these experiments, antiradical activity may be due to
the presence of antioxidant principles in the extract. The free radical scavenging property may be
one of the mechanisms by which this plant is effective in its ethno pharmacological uses against
different ailments. Further studies comprising of phytochemical investigations of the used plant and
evaluation for antioxidant activity using other methods (e.g. various biochemical assays both in
vivo and in vitro) are essential to characterize them as biological antioxidants.
