The antiinflammatory and antioxidant activities of the ethanol extract of Ttifolium resupinatum L. var. microcephalum (Leguminosae) have been assessed on arthritic rats. The extract (1.35 and 13.5 mg/kg, i.p.) significantly reduced the paw edema induced by the complete Freund's adjuvant. Furthermore, it also inhibited lipid peroxidation. These effects of T resupinatum extract may be directly linked to the content in triterpene saponins and flavonoid compounds and consequently to their free radical scavenging activities.
