Stability of<i>d‐a</i>‐tocopherol alone, in solvents, and in methyl esters of fatty acids

Abstract

Summary The stability of d‐a ‐tocopherol in stable solvents and in methyl esters of fatty acids varied with the stability of the medium and with the concentration of tocopherol. Pure tocopherol was less stable than tocopherol in solvents. The concentrations of tocopherol that were most effective in delaying rapid oxidation of the esters were also best for stability of tocopherol itself. The rate of destruction of tocopherol could not be described by simple kinetics.
