Abstract

This study was carries out to analyzed the antioxidant activities and xanthine oxidase inhibitory effects of extracts from jujube to provide basic data for the development of functional materials. Antioxidative activities of extracts from jujube were analyzed by electron donating ability (EDA) using 1,1-diphenyl-2-picryl hydrazyl (DPPH), superoxide dismutase (SOD)-like activity by pyrogallol and nitrite scavenging ability. Extract yields from jujube fruits were 11.55% for unripe fruits, and about twice that value when ripe fruit extracts were prepared. The yields of hot-water and ethanol extracts was 55.67 and 65.95% in dried fruits, respectively. Total phenol contents were higher in unripe fruit extracts. The EDA values of hot-water and ethanol extracts from jujube fruits were increased by increase of extract concentration, and were about 90% in 10.0 mg/mL of extract concentration. The SOD-like activity was increased by the increase of extract concentrations. The SOD-like activity of the hot-water extract from unripe fruits was higher than that of other extracts. The SOD-like activity of ethanol extracts was 39.92% at 10 mg/ml of extract concentration from unripe fruits. The nitrite scavenging ability was about 50% in 1.0 mg/ml of extract concentration at pH 1.2, and that of extracts from unripe fruits was higher than that of other extracts. The xanthine oxidase inhibitory activities of hot-water and ethanol extracts from unripe fruits were higher than those of other extracts, were increased by concentration of extracts.

본 연구는 한방 약용자원으로 사용되고 있는 대추의 효능과 생리활성에 대한 연구의 일환으로 대추 열매의 열수 및 에탄올 추출물의 폴리페놀 화합물과 각 추출물의 항산화활성을 측정하였다. 대추 추출물의 수율은 미숙 대추가 가장 낮은 11% 내외의 수율을 보였으며, 완숙 대추가 미숙 대추보다 2배 이상 높은 수율을 보였고, 건조 대추의 열수 및 에탄올 추출물은 각각 55.67, 65.95%이었다. 대추 추출물의 폴리페놀 함량은 열수와 에탄올 추출물 모두 미숙 대추에서 가장 높았다. 전자공여능은 추출물의 농도가 증가함에 따라 높았고, 10.0 mg/mL의 농도에서는 천연 항산화제인 ascorbic acid와 같이 90% 이상의 전자공여능을 보였다. SOD 유사활성능은 농도가 높아질수록 증가 하였으나, 미숙 대추의 열수 추출물에서 다른 추출물에 비해 높은 SOD 유사활성능을 나타내었다. 에탄올 추출물의 SOD 유사활성능은 미숙 대추 추출물의 10 mg/mL의 농도에서는 39.92%의 SOD 유사활성능을 확인되었다. 대추 추출물의 아질산염 소거능은 pH 1.2와 추출물의 1.0 mg/mL의 농도에서 50% 이상의 소거능을 보였으며, 미숙 대추 추출물에서 가장 높았다. Xanthine oxidase 저해 활성은 미숙 대추의 추출물에서 높았으며, 추출물의 농도가 증가할수록 증가하였다. 이상의 결과에서 실험에 사용한 시료인 미숙 대추, 완숙대추, 건조 대추에는 항산화 물질의 대표적인 폴리페놀 물질도 다량 함유하고 있을 뿐만 아니라 대추의 열수 및 에탄올 추출물로서 항산화성도 우수한 것으로 보여 천연항산화제나 기능성 식품 및 다양한 식품개발에 응용될 수 있을 것으로 생각된다.
