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 fr...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 1D and 2D NMR experiments as well as X- ray diffraction study.展开更多
