Hedera rhomabea bean. 葉의 成分 硏究

Abstract

民間에서 지혈, 육혈, 황달등에 응용되고 있는 송악(常春藤) Hedera rhombea Bean. 잎을 methanol, diethylether, ethylacetate, n-buthanol 순으로 추출분획하여 그 중 n-buthanol ext.에서 compound Ⅰ을 이화학과 광학적 분석에 의하여 3-oxo-20(S)-dammar-24-ene-6α, 20, 26-triol 26-O-β-D-glucopyranoside로 동정하였다.;A dammarane saponin was isolated from the leaves of Hedera rhombea Bean.(Araliaceae). Its MeOH ext. was partitioned into ether, ethylacetate and n-buthanol fractions. The n-buthanol fraction was subjected to silicagel column chromatography using CHCl_(3)/MeOH(20:1) as an eluting solvent to yield compound Ⅰ, colorless needles crystal, m·p 133-135℃. I was elucidated as 3-oxo-20(s)-dammar-24-ene-6α, 20, 26-triol 26-o-β-D-glucopyranoside on basis of spectral data analysis.
