Abstract
The chemical composition of a sample of the title species collected in Pianma, Lushui County, Yunnan Province of China, was examined. Two 3,6,10-oxygenated and two 3,6-oxygenated furanoeremophilanes were isolated. Structures of two new compounds were elucidated. The 3,6-oxygenated furanoeremophilanes were not detected in a sample of the same species previously collected in Laojunshan, Jianchuan County, Yunnan, indicating chemical diversity in the species.

Abstract
From the roots of Ligularia cymbulifera collected in Yunnan Province, China, two new eremophilane-type sesquiterpenoids (1 and 2) together with ten known compounds (3–12) were obtained through the precise chemical component elucidation. The structure determination was mainly carried out with 1D and 2D NMR data.
