A novel eremophilane dimer, named as fischelactone, and a new sesquiterpene lactam, eremophila‐1(10),7(11),8‐triene‐12,8‐lactam, along with ten known compounds, were isolated from the roots of Ligularia fischeri. Their structures were established by means of spectroscopic analyses (EI‐MS, HR‐ESI‐MS, IR, and 1D‐ and 2D‐NMR data) and X‐ray diffraction study.
