- W2472611062 abstract "국내산 양앵두의 유용 생리활성 검토를 목적으로 양앵두 열수 추출물 및 순차적 유기용매 분획물을 조제하였다. 양 앵두 추출물의 약 40%는 당류 성분이었으며, 이의 헥산, 에틸아세테이트, 부탄올 분획물 및 물 잔류물의 분획효율은 각각 0.01%, 3.45%, 16.30% 및 80.24%로 나타나 양앵두 열수 추출물의 대부분이 부탄올 분획 및 물 잔류물로 이행되었다. 에틸아세테이트 분획물은 총 폴리페놀 및 총 플라보노이드 함량이 가장 높았으며, 물 잔류물은 34%의 총당을 함유하였다. 조제된 열수 추출물과 분획물의 항세균 활성을 평가한 결과 에틸아세테이트 및 부탄올 분획에서 Listeria monocytogenes, Staphylococcus aureus, 및 Salmonella typhimurium에 대해 우수한 항세균 활성이 확인되었으며 (MIC, 0.5~1.0 mg/mL), Pseudomonas aeruginosa에는 항균 활성이 나타나지 않았다. 항Candida 활성은 헥산 분획에서만 확인되었으며, 항생제 내성균에 대해서도 우수한 항균 활성을 나타내었다(MIC, 0.5~1.0 mg/mL). 항산화능 평가의 경우 에틸아세테이트 분획에서 우수한 DPPH 소거능( $IC_{50}:195.5;{mu}g/mL$ ) 및 환원력을 나타내었다. 본 연구결과는, 양 앵두가 우수한 항균 활성과 항산화 활성을 가진 유용한 과일자원으로 이용될 수 있음을 제시하고 있다. 【The fruits of sweet cherry are highly appreciated by the consumer due to their precocity and quality, such as their sweetness, color and sourness. In this study, the hot-water extract and its sequential organic solvent fractions were prepared from domestic Napoleon sweet cherry (Prunus avium L.) to investigate antimicrobial and antioxidant activity. The hot-water extract contained about 40% sugars, and the solvent fraction yields for hexane, ethylacetate (EA), butanol, and water residue were 0.01%, 3.45%, 16.30%, and 80.24%, respectively. Contents of total polyphenol and total flavonoid of the fractions were 1.24~5.24%, and 0~3.76%, respectively. Among the fractions, EA fraction showed the highest total polyphenol and total flavonoid concentrations. Evaluation of antimicrobial activity of the extract and fractions revealed that EA fraction and butanol fraction contained strong antibacterial activity against Listeria monocytogenes, Staphylococcus aureus, and Salmonella typhimurium with minimal inhibitory concentration (MIC) of 0.5~1.0 mg/mL. But the extract and fractions tested were not active to Pseudomonas aeruginosa. In a while, only hexane fraction showed anti-Candida activity with 0.5~1.0 mg/mL of MIC. The fraction showed strong activity against different multi-antibiotics resistant strains such as C. albicans CCARM 14020. Antioxidative activity assay showed that EA fraction has a strong DPPH scavenging activity and a reducing power. The $IC_{50}s$ of vitamin E and EA fraction were 15.5 and $195.5;{mu}g/mL$ , respectively. Our results suggest that the fruit of P. avium L. has high potentials with anti-Candida and antioxidative activity.】" @default.
