| Abstract: | Three new eremophilane sesquiterpenes were isolated from the MeOH extract of the roots of Senecio nemorensis. Their structures were identified as 8α‐hydroxy‐6β‐(isobutanoyloxy)‐1‐oxoeremophila‐7(11),9‐dieno‐12,8β‐lactone ( 1 ), 6β,8β‐dimethoxy‐1‐oxoeremophila‐7(11),9‐dieno‐12,8α‐lactone ( 2 ), and 10α‐hydroxy‐6β‐(isobutanoyloxy)‐1‐oxoeremophila‐7(11),8‐dieno‐12,8‐lactone ( 3 ), respectively, based on spectroscopic data, including IR, EI‐MS, HR‐ESI‐MS, and 1D‐ and 2D‐NMR data. |
