Vitamin E Activity of N-Methyl-ß-Tocopheramine in the Rat Reproduction Assay

Laboratory of Nutrition and Endocrinology, National Institute of Arthritis and Metabolic Diseases, National Institutes of Health, Bethesda, Maryland

A derivative of ß-tocopherol, dl,N-methyl-ß-tocopheramine, was compared with dl,a-tocopherol for its vitamin E potency in the rat resorption-gestation bioassay. A relative potency of 88.7 ± 7.4% (confidence limits of 77.1 to 107.4%, P = 0.05) confirms the essentially equivalent activity of dl,N-methyl-ß-tocopheramine and dl,a-tocopherol previously reported in the chick and also in the rat red cell hemolysis test.
