품종이 다른 오디추출물의 Helicobacter pylori에 대한 항균활성 탐색과 항산화 효과

Abstract

The water and ethanol extracts from mulberry fruits were tested for their antimicrobial activities against Helicobacter pylori and antioxidant. Kangwon III (Morus albba L.) was higher phenolic content (2.90 mg/g) than other water extracts. The phenolic contents of ethanol extracts from Kangwon III and Hihak were 3.02 mg/g and 2.46 mg/g, respectively . The ABTS [2,2`-azinobis(3-ethylbenzothiazoline-6-sulfornic acid)] radical decolorization, electron donating ability (EDA), thiobarbituric acid reactive substance (TBARS) and antioxidant protection factor (PF) were determined for water extracts and ethanol extracts from mulberry fruits. EDA was higher in water extracts than ethanol extract. EDA of water extract from Kangwon III was determined as while the activity of ethanol extracts was in Daechoukmyeun. The water extracts from Cheongilppong showed higher antioxidative activity than another mulberry fruits extract when evaluated by ABTS [2,2`-azinobis(3-ethylbenzothiaznoline-6-sulfornic acid)] radical decolorization, TBARS and antioxidant PF by water extracts. Kangwon III was higher phenolic content (2.90 mg/g) than other that of water extracts. ethanol extracts were determined that phenolic contents of Kangwon III, Hihak were 3.02 mg/g, 2.46 mg/g for each other. Antimicrobial activity showed the high value in water extracts of Cheongilppong, Kuksang 20. The result will be useful nature microbial medicine for mulberry fruits.
