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).
A new type of coumarins was isolated from the genus Helicteres angustifolia L. It was named Heliclactone and its chemical structure was deduced by spectroscopy and X-ray diffraction as 6,7-dihydroxy -3,8,11-trimethylcyclohexane embedded [d, e] coumarin (1).
