From Ligularia atroviolacea, four new eremophilendiolides, 81$-hydroxy-eremophil-3,7 （11）-dien-12,8α（14,6α）-diolide （1）, 8β-methoxy-eremophil-3,7（11）-dien-12,8α（14,6α）-diolide （2）, 8α-hydroxy-eremoph...From Ligularia atroviolacea, four new eremophilendiolides, 81$-hydroxy-eremophil-3,7 （11）-dien-12,8α（14,6α）-diolide （1）, 8β-methoxy-eremophil-3,7（11）-dien-12,8α（14,6α）-diolide （2）, 8α-hydroxy-eremophil-3,7（11）-dien-12,8lβ（14,6α）-diolide （3） and eremophil-3,7（11）,8-trien-12,8 （14,6α）-diolide （4）, as well as a known diolide （5） were isolated. Their structures were elucidated on the basis of 1D and 2D NMR as well as ESI-MS spectral data.展开更多
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
