[Spontaneous superweak light of oils by their antioxidant potentional defination]

It was show that by autooxidation of the oleic asid there is as spontaneous superweak light (SSL)--chemiluminescence by forming some unstable peroxides and their decomposition with synthesis of EES--and accumulation of the more stable and chemically titrated peroxides. During a chemically inductive period by native vegetable oils containing bioantioxidants the accumulation of chemically titrated peroxides is depressed completely, but SSL can be fixed and measured, it means there is degrading and forming unstable peroxides with synthesis of EES. As concerns the extent of suppression of SSL and accumulation of some titrated peroxides in the oleic acid by adding native oils the antioxidative activity (AO) of these oils was thoroughly estimated. AO of sunflower oil grown in northern lands is higher than AO of refined oils which have been refined from bioantioxidants. It is revealed that a detailed estimation of an autooxidation process is possible with studying SSL only. We offer here an oleic chemiluminescence-chemical model for a complex AO estimation of examined materials.
