η-Tocopherol (7-Methyltocol) : a New Tocopherol in Rice
Nature, 1956RECENT publications have confirmed the existence of two previously unknown natural tocopherols in the lipid fractions of cereal grains (ɛ- and ζ-tocopherols) and have described methods for their separation by paper chromatography1–3. Thus six of the seven possible tocol structures produced by methylation of the tocopherol chroman nucleus have been ...

Lipids, 1985
AbstractIn rats with hyperlipemia induced by Triton WR‐1339, changes in tocopherol concentrations in plasma and RBC were compared with those in the liver and its subcellular fractions, microsomes and mitochondria.After daily injection with Triton, plssma total lipids at 3 days and 7 days, respectively, showed elevation 6.5 times and 15 times as high as

American Journal of Diseases of Children, 1944
During the last ten years it has been abundantly demonstrated that vitamin E, in addition to being important in reproduction, is essential for the normal development and metabolism of skeletal muscles. The evidence of this function has been summarized recently in an excellent review by Pappenheimer.

Chromatographic separation of tocopherols
Journal of Chromatography A, 2001alpha-, beta-, gamma-, and delta-Tocopherols were separated by reversed-phase high-performance thin-layer chromatography (C18RP-HPTLC), normal-phase high-performance liquid chromatography (NP-HPLC), reversed-phase high-performance liquid chromatography (C18RP-HPLC), and gas chromatography (GC). The selected topological indices based on connectivity (M,

New insights into tocopherol research with emphasis on gamma-tocopherol and delta-tocopherol
2006Vitamin E research in recent years has broadened and changed, with a shift from studies using only synthetic -tocopherol towards the evaluation of other forms, mainly - and -tocopherol. In addition, alternative functions of vitamin E have been proposed, in particular the effects of - and -tocopherol on gene expression. These non-antioxidant functions ¿

Spectrofluorometric determination of tocopherols
Archives of Biochemistry and Biophysics, 1959Abstract A convenient and sensitive method for the differential determination of free and esterified tocopherols utilizing ultraviolet spectrofluorometry is presented. The introduction of a stoichiometric excess of ethereal LiAlH 4 into hydrocarbon solutions of tocopherol esters was found to result in a quantitative cleavage to the free alcohols ...
