The results obtained with the [beta]-carotene
autooxidation inhibition test indicate that the crude ethanolic extract had 60.81%, lower than BHT and BHA but higher than ascorbic acid, since this method is used to evaluate the antioxidant capacity of nonpolar substances.
Involvement of the superoxide anion radical in the
autooxidation of pyrogallol and a convenient assay for superoxide dismutase.
Iwami, Antioxidative Action of Indole Compounds during the
Autooxidation of Linoleic Acid, Euyo Shokuryo, 19, 210 (1996).
They exhibit catalytic effects and participate in different reactions in the
autooxidation process.
Antioxidant properties,
autooxidation, and mutagenic activity of echinochrome a compared with its etherified derivative.
Involvement of the superoxide anion radical in the
autooxidation of pytrogallol and a convenient assay of superoxide dismutase.
These include mitochondrial respiration (electron leakage from electron transport chain and subsequent production of the superoxide radical), prostanoid metabolism, the
autooxidation of catecholoamines, and oxidase enzymatic activity (NAD(P)H oxidase, xanthine oxidase) [18].
Furthermore, the removal of the organic load by physical/chemical and biological processes within the upper layer of the disposal pond (by
autooxidation, sedimentation, degradation) was confirmed.
The
autooxidation of unsaturated fatty acid also leads to emission of volatile aldehydes.
Alternatively, cholesterol can be subject to nonenzymatic
autooxidation, which leads to the formation of a number of cholesterol oxidation products, including 7-ketocholesterol, 7[alpha]-hydroxycholesterol, 7[beta]-hydroxycholesterol, 5, 6[alpha]-epoxy-cholesterol, and 5, 6[beta]-epoxycholesterol.
