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.

A new lactone, heliclactone (I), was isolated from the roots of Helicteres angustifolia and its structure was elucidated on the basis of spectroscopic anal. and x-ray diffraction as 6,7-dihydroxy-3,8,11-trimethylcyclohexo-[d,e]-coumarin.
