calculated to determine the antioxidant activity (AOA). The results showed that there was differ- ence in AOA depending on the antioxidant of used. Tocotrienols were relatively weak compared with the synthetic antioxidant in all different types of oil. The AOA for each antioxidant was dif- fered in different oil types.

alpha-Tocopherol is known as the most abundant and active form of vitamin E homologues in vivo, but recently the role of other forms of vitamin E has received renewed attention. The antioxidant properties were compared for alpha-, beta-, gamma- and delta-tocopherols and tocotrienols. The following results were obtained: (1). the corresponding tocopherols and tocotrienols exerted the same ...

Although the antioxidant and biological properties of tocopherols, especially α-tocopherol, have been extensively investigated, little is known about antioxidant properties of tocotrienols in foods , probably because of the scarcity of these compounds and lower biological vitamin E activity than tocopherols.

This review paper is focused on the relative antioxidant activities of tocopherols and tocotrienols in oils and fats and certain food systems. α-Tocopherol generally showed better antioxidant activity than γ-tocopherol in fats and oils, but at higher concentrations γ-tocopherol was found to be a more active antioxidant. The results of studies on the optimum antioxidant concentrations of ...
