  • Reduction of Alpha-Tocopherol Quinone
    Publication number: 20130041164
    Abstract: ?-tocopherol quinone is chemically reduced by combination with a reducing agent, such as tin (II) ion in the form of stannous chloride (SnCl2-2H20), or by chromium (III) ion, such as chromium (III) in the form of chromium chloride (CrCl3-6H20). Purified ?-tocopherol is obtained from ?-tocopherol formed by reduction of an oxidized ?-tocopherol, such as ?-tocopherol quinone, by tin (II) ion or chromium (III) ion. Purified ?-tocopherol of the invention can be administered to patients in need thereof, ?-tocopherol is preserved by combination with a reducing agent.
