Abstract:
We tested the antioxidant properties of both aqueous and methanolic extracts of oregano (origanum vulgare) They proved to be effective in the inhibition of all phases of the peroxidative process: first neutralizing free radicals (superoxide anion, hydroxyl radical and 1,1-diphenyl-2-picrylhydrazyl radical), then blocking peroxidation catalysis by iron (through iron-chelating and iron-oxidizing properties), and finally through interruption of lipid-radical chain reactions (chain-breaking activity). Their anti-glycosylation activity was also effective. The glycosylation of lipoproteins is directly related to their peroxidation. The amount of extract used in our experiments was obtained from 0.1-1 mg of dried leaves, amounts far less than those normally used in the Mediterranean diet.
