Abstract
The present investigation focuses on the methanolic extract obtained from Geranium robertianum L. (Geraniaceae) (Herb Robert), a herbal plant used in traditional medicine for the treatment of human and animal diseases. The antioxidant capacities of the extract were evaluated using 1,1-diphenyl-2- picrylhydrazyl radical, β-carotene/linoleic acid and reducing power and metal chelating activity assays. The amount of total phenolic content, flavonoids and condensed tannins was very high, and the correlation between the antioxidant activity potential and total phenolic level of the extract was pointed out.
