Özet
The antioxidant properties of Rhamnus petiolaris Boiss., R. rhodopeus Velen. subsp. anatolicus (Grub.) Browicz & Ziel., and R. thymifolius Bornm., three endemic species occurring at altitudes of 1000–1200 meters on volcanic rock around Afyonkarahisar was evaluated. Antiradical activity of Rhamnus petiolaris Boiss., R. thymifolius Bornm. and R. rhodopeus Velen. subsp. anatolicus (Grub.) Browicz & Ziel was found 0.47, 0.56, and 0.68 respectively. Chelation of the samples via Fe 2+ ranged from 38.78 % to 54.79 %. R. rhodopeus Velen. subsp. anatolicus (Grub.) Browicz & Ziel showed the highest chelation via Fe 2+ , which was 54.79 %. Another method to determine the antioxidant activity of the samples was elimination of H O, which appeared to be 36.12 % in Rhamnus petiolaris Boiss., 53.89 % in R. thymifolius Bornm., and 68.73 2 % 2 in R. rhodopeus Velen. subsp. anatolicus (Grub.) Browicz & Ziel. Also for this test, R. rhodopeus Velen. subsp. anatolicus (Grub.) Browicz & Ziel exhibited the highest antioxidant activity. © 2011, Copyright Har Krishan Bhalla & Sons.
