Vitamin E and correlated antioxidants: a gamma radiolysis study.
gamma irradiations of Vit.E-Vit.C aerated ethanolic solutions have been performed for several ratios (Vit.E)/(Vit.C) between 0.1 and 50. The obtained results show that Vit.C is able to regenerate Vit.E from its oxidized radical, this regeneration being total for a ratio (Vit.E)/(Vit.C) greater than or equal to 27 in our conditions of irradiation. The ratio (Vit.E)/(Vit.C) seems to be the main factor of this synergestic effect towards peroxyl radicals scavenging.
