Abstract. The quantities of O2?- and ?OH of Astragalus onobrychis
Var Chlorocarpus (Gris.) Stoj et Stef. (Leguminosae) and Oxytropis pilosa
(L.) DC. produced from three different growth stages during 1995 at the
locations Korvin grad (near Doljevac) and Subotinac (near Aleksinac), Serbia,
were examined. The highest quantity of O2?- was found in the root of Astragalus
in the seed forming stage (3053.49 nmol/g fresh material). The highest
quantity of O2?- in Oxytropis was also found in its root but in the blooming
stage (2894.56 nmol/g fresh material). The root of Astragalus contained
the highest quantity of ?OH (30.20 nmol/g fresh material) in the blooming
stage. The leaves of Oxytropis in the same stage of growth contained 15.90
nmol/g fresh material.
Key words: Astragalus onobrychis Var. Chlorocarpus (Gris.) Stoj.
et Stef. (Leguminosae), Oxytropis pilosa (L.) DC., oxygen radicals, leguminosae.
KISEONIČNI RADIKALI
U ASTRAGALUS ONOBRYCHIS I OXYTROPIS PILOSA
Ispitivana je količina O2?- i ?OH u korenu, stablu i listu vrsta Astragalus
onobrychis Var. Chlorocarpus (Gris.) Stoj. et Stef. (Leguminosae) i Oxytropis
pilosa (L.) DC. sa staništa Korvin grad (u blizini Doljevca) i Subotinac
(u blizini Aleksinca) tokom vegetacionog perioda u 1995. godini. Najveća
količina O2?- je ustanovljena u korenu Astragalus-a (3053,49 nmol/g, svež
uzorak) u fazi formiranja semena. U korenu Oxytropis-a je takođe utvrđena
najveća količina superoksid radikala (2894,56 nmol/g, svež uzorak) ali
u fazi cvetanja. Koren Astragalus-a u fazi cvetanja sadrži najviše ?OH
(30,20 nmol/g, svež uzorak). List Oxytropis-a u istoj fazi vegetacije
sadrži 15,90 nmol/g, svež uzorak, ?OH..
