摘要
目的:研究玉竹的化学成分.方法:运用各种分离方法(硅胶柱层析,Sephadex LH-20)分离化合物,根据理化性质和波谱数据鉴定化合物的结构.结果:从玉竹中分离并鉴定了4个高异黄酮类化合物,结构分别为(±)5,7-dihydroxy-3-(2-hydroxy-4-methoxybenzyl)-6,8-dimethylchroman-4-one (1), (3R)-5,7-dihydroxy-3-(4-hydroxybenzyl)-6,8-dimethylchroman-4-one(2),(3R)-5,7-dihydroxy-3-(4-hydroxybenzyl)-8-methoxy-6-methylchroman-4-one(3),(3R)-5,7-dihy-droxy-3-(4-hydroxybenzyl)-6-methylch-roman-4-one(4).结论:高异黄酮类化合物在自然界很少见.
Abstract
AIM: To study the chemical constituents from the rhizome of Polygonatum odoratum (Mill.) Druce.METHODS: The chemical constituents were isolated by chromatographic separations of silica gel and Sephadex LH-20 and their structures were elucidated on the basis of spectral analysis. RESULTS: Four homoisoflavanones were isolated and identified as (±)5, 7-di-hydroxy-3-(2-hydroxy-4-methoxybenzyl)-6,8-dimethyichroman-4-one (1), (3R)-5,7-dihy-droxy-3-(4-hydroxybenzyl)-6,8-dimethylchroman-4-one (2), (3R)-5,7-dihydroxy-3-(4-hydroxybenzyl)-8-methoxy-6-methylchroman-4-one (3), and (3R)-5,7- dihydroxy-3-(4-hydroxybenzyl)-6-methyl- chroman-4-one (4). CONCLUSION:Homoisoflavanones were rare in nature.
