우리나라 중부 이남의 산야에서 자생하는 청미래 덩굴에 대해 다양한 생리활성을 가진 기능성 식품 소재로서의 이용 가능성을 모색하기 위하여 그 잎을 열수 및 에탄올로 추출한 후 추출물의 총 폴리페놀 및 플라보노이드 함량, 항산화 활성, 아질산염 소거능 및 항균 활성 등을 검토하였다. 청미래 덩굴 잎의 열수 추출물과 에탄올 추출물에는 총 폴리페놀이 각각 및 함유되어 있었고, 플라보노이드는 각각 및 함유되어 있었다. DPPH radical 소거
Hot-water and 70%-ethanol Smilax china leaf extracts were prepared, and their total polyphenol and flavonoid contents, DPPH-radical-scavenging ability, nitrite-scavenging ability, and antimicrobial activity were determined. The total polyphenol contents of the hot-water and ethanol extract were and , respectively; their flavonoid contents were and ; their DPPH-radical-scavenging abilities, assayed at 1.0 mg/mL, were 33.6 and 92.3%; and their nitrite-scavenging abilities, assayed at 0.1-2.0 mg/mL, were 37.9-61.6 and 38.4-77.8%. The 70%-ethanol extract showed higher antimicrobial activity than the hot-water extract. The antimicrobial activities were high in Bacillus cereus, Vibrio parahaemolyticus, Salmonella typhymurium, and Staphylococcus aureus, in that order. The antimicrobial substances in the two extracts were maintained after heating at for 30 min.
