要約
The autoxidation of linoleic acid and methyl linolenate is inhibited by flavonoids. The antioxidant efficiency of these flavonoids increases with their concentration and in the order fustin < catechin < quercetin < rutin = luteolin < kaempferol < morin for linoleic acid and rutin < catechin < morin = kaempferol for methyl linolenate. Flavonoids are more effective on linoleic acid than on methyl linolenate. The antioxidant activity of flavonoids is related to an inhibition of the formation of trans,trans hydroperoxide isomers of linoleic acid. This inhibition exhibited the great H-atom donating ability of flavonoids to peroxy radical, thus terminating the chain radical reaction.
