From the roots of Ligularia macrophylla, a bisesquiterpene, ligumacrophyllal was isolated and its structure was elucidated on the basis of spectroscopic methods.
Two new eremophilane sesquiterpenes, 15β-formic ether-6-oxo-furanoeremophilane （1） and 6α, 15β-epoxy eremophila-7（11）-en-8α, 12-olide （2） were isolation from the roots of Ligularia macrophylla.

Their structures were deduced from spectroscopic methods and 2D NMR experiments.展开更多
