【摘要】 从梧桐科植物山芝麻(Helicteres angustifolia L.)中又分离出一新型香豆素类化合物,命名为山芝麻内酯(Heliclactone).其化学结构经波谱和 X 衍射推定为6,7-二羟基-3,8,11-三甲基环己烷嵌[d,e]香豆素(1).更多还原

【Abstract】 A new lactone heliclactone,was isolated from the roots of Helicteres angustiolia L.and it’s sturcture was elucidated on the basis of spectroscopic analysis and X-ray diffrac-tion as 6,7-dihydroxy-3,8,11-trimethylcyclohexo-[d,e]-coumarin(1).更多还原
