ANTIOXIDANT PROPERTIES OF DESFERRIOXAMINE-E, A NEW HYDROXAMATE ANTIOXIDANT

Antioxidant properties of desferrioxamine E, a cyclic trihydroxamate p roduced by microorganism, were A tested and compared to those of desfe rrioxamine B and butylated hydroxyanisole (BHA). Desferrioxamine E exh ibited significant antioxidant effects in linoleic acid emulsions as w ell as in emulsions of linoleic acid and beta-carotene. In concentrati ons of 100 ppm, the effect of both desferrioxamines in linoleic acid e mulsion was equal to that of BHA. The antioxidant activity of the desf errioxamines in emulsions of beta-carotene and linoleic acid was signi ficantly higher than that of BHA. In addition, the initial rate of bet a-carotene destruction was significantly lower when desferrioxamines w ere added to the emulsion.
