Abstract
Two stilbenoids and two flavonoids were isolated from ethylacetate fraction of ethanol extract of Morns bombycis heartwood. These four compounds were identified 2',3,4',5-tetrahydroxystilbene(oxyresveratrol), 3,4',5-trihydroxystilbene (resveratrol) as stilbenoids, and 2',3,4',5,7-pentahydroxyflavone(morin), 3,4',5,7-tetrahydroxyflavan((+)-afzelechin) as flavonoids by Mass and NMR spectroscopic analysis.
항균 및 항산화활성이 우수한 산뽕나무(Morus bombycis)로부터 항균 및 항산화물질 탐색을 위해 심재 에탄올 추출물을 용매분획하여 얻은 에틸아세테이트 가용부로부터 4개의 페놀성 화합물을 단리하였다. 이들을 기기분석한 결과, stilbenoid 인 2',3,4',5-tetrahydroxystilbene(oxyresveratrol), 3,4',5-trihydroxystilbene(resveratrol)과 flavonoid인 2',3,4',5,7-pentahydroxyflavone(morin) 및 3,4',5,7-tetrahydroxyflavan ((+)-afzelechin)인 것으로 동정되었다.
