Inhibitions of the autoxidation of linoleic acid by flavonoids in micelles.
The activities of five flavonoids as chain-breaking antioxidants have been studied for the autoxidation of linoleic acid in cetyl trimethylammonium bromide (CTAB) micelles at 37 degrees C. Flavonols such as quercetin, rutin and morin exhibited antioxidant activities, while two flavanones, naringin and hesperidin, did not suppress the oxidation appreciably. The ratio of rate constants for inhibition and propagation kinh/kp and stoichiometric factor n were determined.
