| Popis: | 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 Fe2+ ranged from 38.78 % to 54.79 %. R. rhodopeus Velen. subsp. anatolicus (Grub.) Browicz & Ziel showed the highest chelation via Fe2+, 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 68.732 %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 antioxi... |
