"Various experiments are reported on the conversion of α-tocopheroxide to α-tocopherol and to α-tocopherylquinone; under weakly acidic conditions α-tocopheroxide readily forms α-tocopherylquinone, whereas under similar conditions with ascorbic acid present α-tocopherol is formed. "
"Ascorbate and α-tocopherol act synergistically in the prevention of the acceleration by cytochrome c of the oxidation of linoleate near neutral pH. Neither α-tocopheroxide or α-tocopherylquinone are effective with or without ascorbate."
