Abstract:
The antioxidative properties of bulb, leaf and stalk of Allium ursinum were investigated. Activities of antioxidant enzymes (superoxide dismutase, catalase, peroxidase, glutathione peroxidase), quantities of malonyldialdehyde, superoxide and hydroxyl radicals and reduced glutathione and also the contents of total flavonoids, chlorophylls a and b and carotenoids were determined. The extracts from all plant organs exhibited antioxidant activity, the highest having been observed in the leaves. Furthermore, ESR signal of PBN-OH radical adducts in the presence of leaves phosphate buffer (pH 7) extract was reduced for 87.61%.
