Abstract

The chemical constituents of the root of Ligularia duciformis, collected in Yunnan Province of China, was studied and two new oplopane-type sesquiterpenoids were isolated, whose structures were determined on the basis of spectroscopic evidence. Quite recently, oplopane-type compounds were found in Ligularia narynensis, and this is the second example to isolate oplopane-type sesquiterpenoids from Ligularia plants.
