A reassessment of tocopherol chemistry
Biochemical and Biophysical Research Communications, 1964Abstract This paper describes the presence in Nature of four methylated tocols (the 8-monomethyl, 5,8- and 7,8-dimethyl and 5,7,8-trimethyl derivatives) and the four related tocotrienols (for nomenclature see Bunyan, McHale, Green and Marcinkiewicz, 1961 ).

Lipids, 1971
AbstractMethods are now available for the determination of all the specific tocopherol forms found in nature. Although the greatest interest centers on alpha‐tocopherol, much information has been gathered on the amounts of individual tocopherols in foods and fats contributing to the human diet.

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 ...
