Abstract

In order to find a novel antioxidant source from nature, the comparison of antioxidative activity was carried out through the CDM(conductometric determination method) with various crude drugs on palm oil, lard and soybean oil. After the preliminary experiment, we concluded that the turmeric (Curcumae Rhizoma) ethanol extract has the strongest antioxidative activity among the ten crude drugs. In case of over 0.05% of concentration turmeric ethanol extract, it has more activity than others athough the turmeric ethanol extract has similar antioxidative activity to tocopherol and rosemary extract up to 0.05% of concentration. The turmeric ethanol extract of 0.01% was more effective in lard (AI=4.59) than in palm oil (AI=1.57) and ineffective in soybean oil. When turmeric ethanol extract was added to various kind of fatty acid methyl esters at 0.05% and 0.1% respectively, the antioxidative index(AI) on oleic acid methyl ester was greatly increased, whereas the antioxidative index on linoleic acid methyl ester was decreased.
