Phytochemical investigation of the whole plant of Ligularia fischeri afford
ed two new sesquiterpenes 11 -hydroxy-eremophil 1(10)-en-2,9-dione (1); and
1 beta ,11 -dihydroxy-eremophil-9-ene (2); four known compounds (-)-4 beta
,7 alpha -aromadendranediol (3), 1 beta ,6 alpha -dihydroxyeudesm-4(15)-en
e (4); Teucdiol A (5); Teucdiol B (6). The new compound structures were elu
cidated by spectroscopic methods including 2D-NMR techniques.
