| Abstract: | Phytochemical investigation of the whole plant of Ligularia fischeri afforded two new sesquiterpenes 11‐hydroxy‐eremophil 1(10)‐en‐2,9‐dione (1) ; and 1β,11‐dihydroxy‐eremophil‐9‐ene (2) ; four known compounds (‐)‐4β,7α‐aromadendranediol (3) ; 1β,6α‐dihydroxyeudesm‐4(15)‐ene (4) ; Teucdiol A (5) ; Teucdiol B (6) . The new compound structures were elucidated by spectroscopic methods including 2D‐NMR techniques. |
