Methanol extracts of nine species of Geraniaceae, namely G. sylvaticum L., G. sanguineum L., G. columbinum L., G. caeruleum Schur, G. pyrenaicum Burn.fill, G. lucidum L., G. marcorrhizum L., G. robertianum L. and Erodium cicutarium (L.) L'Hér, were studied for their antioxidant properties. DPPH (1,1-diphenyl-2-picryl hydrazyl) radical assay was used. The all examined extracts exhibited considerable free radical scavenging activity and their IC50 values were below 50 microg/mL. The tested species were poor studied with the exception of G. sanguineum and G. marcorrhizum. The antioxidant potential of newly studied species is commensurable with G. sanguineum, well known and widely used in herbal medicine. The obtained results indicated that Geraniacean species extracts are potential source of antioxidant activity.
