Three new compounds,including one chloro-furoeremophilanoid (1),one eremophiladiolide (2),a rare dimer of nor-furoeremophilanoid,ligulatrovine A (3),and a known furoeremophilanolide (4),were isolated from Ligularia atroviolacea.The structures of compounds 1-4 were elucidated by spectroscopic methods including ID and 2D NMR experiments as well as X-ray diffraction study.
