8β-hydroxyeremophil-7(11)-ene-12,8α(4β,6α)-diolide was isolated from the Ligularia intermedia and characterized by MS, multi NMR and X-ray single crystal diffraction. Its crystal structure was determined as in a orthorhombic type, with space group P212121 with a=6.8519(5), b=10.7191(8), c=18.5942(14) (A),V=1365.67(18) (A)3, Z=4, and the calculated density is 1.354 mg/m3. F(000)=592, μ=0.101 mm-1.
