유색감자 홍영 및 자영 추출물의 생물학적 활성 비교

초록

This experiment was conducted to enhancethe colored potatoes utilization and to determine the bio-logical activity of colored potato extracts. In order to under-stand the factors responsible for the potent antioxidant abi-lity of colored potatoes, it has been evaluated for anti-oxidative activity using oxygen radical absorbance capacity(ORAC) assay. Hongyoung extract was ignificant anti-oxidant activities in ORAC assay. About two-fold higherradical absorbance capacity was found in Hongyoung com-pared to that in Jayoung. The ability of 80% ethanolactivity of nitric oxide (NO) and nitric oxide synthase (iNOS),cyclooxygenase-2 (COX-2) has also been investigated. Thevarious therapeutic benefit claims in the new functionalmedicinal usage of colored potatoes ascribed to the phenoliccompounds and anthocyanin. This result revealed that theextracts of colored potatoes are expected to be good can-didate for development into sources of free radical sca-venger or COX-2 inhibiting agents.
