초록
큰잎자작 변재의 메탄올(methanol, MeOH) 조추출물로부터 silica gel column, CPC 등의 크로마토그라피를 이용하여 4종의 화합물을 단리하였으며, 단리물질에 대한 NMR 등의 기기분석 결과, flavonoid 및 lignan 배당체인 catechin 7-O-𝛽-D-xylopyranoside, lyoniresinol 9'-O-𝛽-D-glucopyranoside, 그리고 diarylheptanoid인 11-oxo-3, 8, 12, 17-tetrahydroxy-9-ene [7, 0]-metacyclophane 및 11-oxo-3, 8, 9, 10, 12, 17-hexahydroxy [7, 0]-metacyclophane으로 각각 동정하였다.
One flavonoid, lignan glycosides and two diarylheptanoids were isolated from the sapwood of Betula maximowicziana. The structures were determined as : catechin 7-O-𝛽-D-xylopyranoside, lyoniresinol 9'-O-𝛽-D-glucopyranoside, 11-oxo-3, 8, 12, 17-tetrahydroxy-9-ene[7, 0]-metacyclophane and 11-oxo-3, 8, 9, 10, 12, 17-hexahydroxy[7, 0]-metacyclophane, respectively, on the basis of spectrosopic data and chemical correlations.
