Popis: Antioxidant and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities, reducingpow-ers and the amount of total phenolic compounds of some medicinal Asteraceae species used in folk med-icine in Eastern Anatolia were studied. These species are Achillea biebersteinii, Achillea wilhelmsii, Artemisia absinthium, Artemisia austriaca, Cichorium intybus, Helichrysum arenarium subsp. rubicun-dum, Tripleurospermum oreades var. oreades. The highest antioxidant activity is shown by methanol extract of A. austriaca followed by water extract of A. austriaca, methanol extract of A. wilhelmsii, water extract of H. arenarium, water extract of A. biebersteinii, water extract of A. absinthium, water extract of C. intybus, water extract of A. wilhelmsii, water extract of T. oreades. The highest DPPH radical scavenging activity is also shown by methanol extract of A. austriaca followed by water extract of A. austriaca, water extract of H. arenarium, water extract of A. absinthium, water extract of A. bieber-steinii, water extract of C. intybus, water extract of A. wilhelmsii, water extract of T. oreades, methanol extract of A. wilhelmsii. Özet Dogu Anadolu’da halk arasinda tedavi amaciyla kullanilan bazi Asteraceae türlerinin antioksidan, 2,2-difenil-1-pikrilhidrazil (DPPH) radikal süpürücü aktiviteleri, indirgeme güçleri ve total fenolik bilesik miktarlari arastirilmistir. Bu türler, Achillea biebersteinii, Achillea wilhelmsii, Artemisia absinthium, Artemisia austriaca, Cichorium intybus, Helichrysum arenarium subsp. rubicundum ve Tripleurospermum oreades var. oreades’den olusmaktadir. En yüksek antioksidan aktivite A. austria-ca’niin methanol ekstresinde gözlenmistir; bunu sirasiyla A. austriaca su ekstresi, A. wilhelmsii metanol ekstresi, H. arenarium su ekstresi, A. biebersteinii su ekstresi, A. absinthium su ekstresi, C. intybus su ekstresi, A. wilhelmsii sulu ekstresi ve T. oreades sulu ekstresi izlemektedir. En yüksek DPPH radikal süpürücü aktivite A. austriaca’nin methanol ekstresinde gözlenmistir; bunu sirasiyla A. austriaca su ekstresi, H. arenarium su ekstresi, A. absinthium su ekstresi, A. biebersteinii su ekstresi, C. intybus su ekstresi, A. wilhelmsii su ekstresi, T. oreades su ekstresi ve A. wilhelmsii metanol ekstresi izlemektedir.
