title: [Chemical constituents from roots of Ligularia intermedia].
abstract: A new sesquiterpenoid, 8α-hydroxy-6β-methoxy-1-oxoeremophila-7 (11), 9 (10) -diene-12, 8-olide (1) and five known compounds, petasin (2), caffeic acid (3), hepta-cosanol (4), β-sitosterol (5) and β-daucosterol (6) have been isolated from the roots of Ligularia intermedia. The compounds were isolated by column chromatography on silica gel and Sephadex LH-20, and identified based on spectral analyses (MS, 1H-NMR, 13C-NMR).
