본 연구는 뜰보리수 열매의 식품영양학적 평가 및 기능성 물질 발굴의 일환으로 뜰보리수 열매를 이용하여 성숙과정 중의 free radical 소거능을 비롯한 SOD유사활성, 아질산염 소거작용, xanthine oxidase 저해활성 등의 항산화 활성을 조사하였다. 뜰보리수 에탄올 추출물의 전자공여능은 성숙함에 따라 감소하는 경향을 나타내었으며, 에탄올 추출물의 농도가 높을수록 전자공여능의 효과는 더욱 높게 나타났다. 에탄올 추출물의 SOD 유사활성
This study was designed to analyze the election donating ability(EDA), superoxide dismutase(SOD)-like activity, nitrite scavenging ability and xanthine oxidase for food nutritional evaluation and excavation of functional materials in fruits of Elaeagnus multiflora THUNB. The electron donating ability of ethanol extracts in the 1.0 mg/ml concentration of extract was higher in extract of unripe fruits than others. The superoxide dismutase (SOD)-like activity was increased according to increasing of the extract concentration. The SOD-like activity was highest in the extract of unripe fruits among the extracts. The nitrite scavenging ability of unripe fruits ethanol extracts in 1.0 mg/ml of extraction solution in pH 1.2 was higher than extract of ripe and Ovenipe fruits. The nitrite scavenging ability was decreased according to increasing of pH. Also, inhibition of xanthine oxidase activity were higher in extracts of unripe fruits than those in extract of ripe and over-ripe fruits.
