Achillea millefolium (Asteraceae, yarrow) has been used in folk medicine against several disturbances including skin inflammations, spasmodic and gastrointestinal disorders. In this study, ethanol and water extracts were prepared from A. millefolium flowers, leaves and seeds. Antioxidant activities were measured by ferric thiocyanate method, and H2O2radical scavenging activity assays and phenolic compounds and flavonoid contents of A. millefolium extracts were also determined. In conclusion, extracts of A. millefolium flowers, leaves and seeds had effective H2O2radical scavenging activity, total antioxidant activity, and these antioxidant activities were compared with BHA and ?tocopherol as reference antioxidants
