The objective of this study was to investigate the antioxidative acitivities of various solvent extracts from haw (Crataegus pinnatifida Bunge) pulpy. The Freeze-dried pulpy of haw was extracted with five solvents (70% methanol, 70% ethanol, chloroform:methanol (CM, 2:1, v/v), n-butanol, and ethyl a...

산사 과육을 용매별로 추출한 후 항산화 활성을 조사한 실험에서 항산화 활성이 가장 높게 나타난 추출물은? | 05). 본 실험 결과 산사 과육 추출물의 항산화 활성은 우수한 것으로 나타났고 특히, 70% methanol 및 70% ethanol 추출물에서 높은 활성을 보였다. 따라서 산사는 천연 항산화제 및 기능성 식품 소재로서 활용될 수 있을 것으로 생각된다. | |
산사에 함유된 약리성분은? | 산사(Crataegus pinnatifida Bunge)는 특유의 향과 맛을 가지고 있는 장미과(Rosaceae)의 열매로 우리나라 및 중국, 일본 전역에 자생하고 있으며 예로부터 소화기 질환, 고혈압, 항비만 등의 질환에 이용되어 왔다(7,8). 생산사의 미네랄 함량은 칼륨이 제일 높다고 알려져 있는데 그 밖에 칼슘, 인, 망간, 아연, 철분, 구리 등의 영양 성분도 함유되어 있다고 하며(9) corosolic acid, (-)-epicatechin, cyanidin-3-galactoside, isoquercitrin, hyperoside 등의 약리성분도 포함하고 있다고 한다(10,11). 또한, 산사 phenol compound의 대부분을 차지 하는 것은 quercetin이며 hyricetin, gentisic acid, caffeic acid, catechin, salicylic acid, ferulic acid, chlorogenic acid, narigin, ρ-coumaric acid도 포함되어 있다고 보고된 바 있다(12). | |
산사 phenol compound에는 어떤 것들이 있는가? | 생산사의 미네랄 함량은 칼륨이 제일 높다고 알려져 있는데 그 밖에 칼슘, 인, 망간, 아연, 철분, 구리 등의 영양 성분도 함유되어 있다고 하며(9) corosolic acid, (-)-epicatechin, cyanidin-3-galactoside, isoquercitrin, hyperoside 등의 약리성분도 포함하고 있다고 한다(10,11). 또한, 산사 phenol compound의 대부분을 차지 하는 것은 quercetin이며 hyricetin, gentisic acid, caffeic acid, catechin, salicylic acid, ferulic acid, chlorogenic acid, narigin, ρ-coumaric acid도 포함되어 있다고 보고된 바 있다(12). 산사의 생리활성으로는 트롬빈 저해 활성(13), 위장보호(14), 지방 세포의 분해(15), 혈청 및 간의 지질 농도 개선(16), 기억력 개선(17) 등의 작용이 있다고 보고되어 있다. |
