Abstract (2. Language): 
The present study was carried out to determine of Centaurea Pterocaula which was collected in region of Konya Tuz Lake. It was extracted with petroleum ether using a soxhleth apparatus for remove it's oil. Then the defatted plant materials were extracted with 70% methanol.and concentrated. Total phenol concentration was determined by Folin-Ciocalteu method, free radical scavenging activities were determined based on DPPH and determined reducing power based on Oyaizu method. The phenolic compound of C. Pterocaula was elucidated by HPLC analysis. Results were compared with standard antioxidant compound BHA and BHT.
Abstract (Original Language): 
Bu çalışmada Konya Tuz Gölü civarından toplanan Centaurea Pterocaula'nın antioksidan aktivitesinin belirlenmesi amaçlanmıştır. Centaurea Pterocaula 'u yağından uzaklaştırılmak için sokslet apareyi ile petrol eterinde ekstrakte edildi. Sonra materyal %70 lik metanolde tekrar ekstraksiyona tabi tutuldu ve çözücüsünden uzaklaştırıldı. Toplam fenolik madde konsantrasyonu Folin-Ciocalteu metoduna, serbest radikal süpürme etkisi DPPH metoduna göre ve indirgeme gücü ise Oyaizu metoduna göre yapıldı. Bitkinin fenolik yapısı HPLC ile belirlendi. Sonuçlar sentetik antioksidan olan BHT (Butillenmişhidroksitoluen) ve BHA (Butillenmişhidroksianisol) ile kıyaslandı.
