Abstract
The antioxidative activity of α-and γ-tocotrienols in methyl linoleate was tested by weighing method at 60°C and was compared with that of α- and γ-tocopherols. Tocotrienols showed slightly superior or equal antioxidative activity to the corresponding tocopherols. To confirm the activity of the isopentenoid side chains of tocopherols, α-tocotrienyl acetate and squalene were tested. Neither substance showed any particular antioxidative or prooxidative activity.
