dc.description.abstractThe present study aims to evaluate the antioxidant efficacy and the lipid peroxidation degree of Sambucus nigra L. (S. nigra) blossom extract after induction of biotic stress. Dry stained extracts of S. nigra flowers were analyzed by direct and indirect in vitro EPR spectroscopy. The antioxidant activity of the extract was assessed by DPPH analysis, and the inhibition of lipid peroxidation - by PBN-spin adduction, after UV-B and thermal stress. The direct EPR stable radical structures presence was established either in non-irradiated and UV-B irradiated samples. Furthermore, as before and after UV-B and thermal biotic stress, S. nigra showed well-expressed scavenging abilities and protective properties against reactive oxygen and nitrogen species such as superoxide radicals (•O2̅ ), hydroxyl radicals (•OH), and reduced lipid peroxidation
