| Abstract: | The effect of flavonoids of various structures (baikalein, baikalin, quercetin, dihydroquercetin, genistein, and daidzein) on the process of formation of lipid hydroperoxides during thermoinduced autooxidation of neutral lipids of animal origin is studied. The minimum inhibitory concentration of isoflavones was found to be equal to 10-3 M. The effective inhibitory concentration of other flavonoids (except baikalin) was equal to 10-4 M. Baikalin was an effective promoter of lipid peroxidation. The antioxidant activity of the flavonoids tested was calculated, taking ionol as a reference.Translated from Prikladnaya Biokhimiya i Mikrobiologiya, Vol. 41, No. 1, 2005, pp. 23–28.Original Russian Text Copyright © 2005 by Antoshina, Selishcheva, Sorokoumova, Utkina, Degtyarev, Shvets. |
