The roots of Ligularia intermedia yielded four benzofurans, a novel phenol derivative, 2-isopropenyl-6-acetyl-8-methoxy-1,3-benzodioxin-4-one, and three substituted geranyls, including two new hydroperoxide compounds, (E)-4-(6-hydroperoxy-3,7-dimethylocta-2,7-dienyloxy)-syringenin and (E,E)-4-(7-hydroperoxy-3,7-dimethylocta-2,5-dienyloxy)-syringenin. Structures were elucidated using chemical and spectroscopic methods.
