A study was carried out on the antioxidant property of Aframomum danelli
extract in palm oil and soybean oil. The activity of A. danielli extract was compared with those of other antioxidants of other plant sources, rosemary extract and d-tocopherol, at different concentrations. A. danielli
was as active as rosemary plant extract in reducing rate of peroxide tbrmation in soybean oil at concentrations of 2OOppm and 3OOppm . A danielli
was much more effective than tocopherol in reducing peroxidation in soybean oil and palm oil at the higher concentrations except at 50 ppm.
