Abstract

The antioxidant activities of the seven tocopherols and of the unmethylated parent compound (tocol) have been compared in several systems.

The three tocopherols unsubstituted in the 5‐position (δ, γ and η) were more effective than the other four in protecting carotene in mineral oil solution at 75°.

In lard esters at 90° and in methyl linoleate at 50° δ, γ, η and β were the most, and ϵ, ζ and α the least, effective, the precise order depending on the conditions and concentrations used. the tocopherols were much less effective in protecting lard esters exposed to light, δ being the best of the series.
