Possible Interaction: Antioxidants and Tocopherols

“8‐Isoprostane, a marker of oxidative stress in the …, was also reduced by γ‐TmT. Noticeably, γ‐TmT stimulated …‐dependent antioxidant response in the mammary glands of E2 treated rats, evident from the induced mRNA levels of Nrf2 and its downstream antioxidant enzymes, superoxide dismutase, catalase, and glutathione peroxidase.”

“It is suggested that these more specific measures for carotenoids and tocopherols would increase the accuracy of estimating health impacts of antioxidant vitamins in the study population.”

“The tocols present in palm oil are natural biological antioxidants and can therefore augment the antioxidant potential of Indian diets.”

“γ‐T‐enriched mixed tocopherols significantly up‐regulated the expression of Nrf2 and its related detoxifying and antioxidant enzymes thereby suppressing PIN and tumor development.”

“Whereas it seems clear that the need for tocopherols in the diet is modified by the administration of certain synthetic anti-oxidants , the question of the nutritional dispensability of vitamin E has not been resolved by the experiments cited.”

“The effectiveness of antioxidants decreased in the following order: phenolic compounds from rapeseed meal>rosemary extract>mix of tocopherols from rapeseed oil>mix of synthetic tocopherols>green tea extract>sinapic acid>BHT.”

“Practical applications: Tocopherols as naturally present antioxidants influence considerably the antioxidant activity of other antioxidants added to plant oils used as a test medium.”
