| Abstrakt: | Unlabelled: Many recent studies have showed that onion (Allium cepa L.) has antioxidant effect which could be of great importance for prevention and treatment of different diseases: diabetes, cancer, cardiovascular and neurodegenerative disorders. The aim of this study was to investigate the antioxidant capacity of two extracts isolated from fresh onion bulbs: an hydroalcoholic extract (codified EC1) and an aqueous extract (codified EC2). Methods: Antioxidant capacity was evaluated by three different assays: DPPH scavenging assay, H2O2, scavenging assay and reducing power assay. Results: Both investigated extracts possess interesting antioxidant properties which are significantly influenced by their chemical composition. |
