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

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

A derivative of β-tocopherol, dl,N-methyl-β-tocopheramine, was compared with dl,α-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-meth...

Zusammenfassung:A derivative of β-tocopherol, dl,N-methyl-β-tocopheramine, was compared with dl,α-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-β-tocopheramine and dl,α-tocopherol previously reported in the chick and also in the rat red cell hemolysis test.
