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.
천연물로부터 안전성과 안정성이 우수한 항산화성 물질을 찾기 위하여 생약류 10종을 선정하여 95% ethanol으로 추출하면서 추출 수율과 팜유를 기질로한 항산화력을 비교한 결과 울금이 가장 좋은 것으로 나타났다. 이러한 울금 추출물을 팜유에 대해 첨가농도를
