Two new dibenzofurans, 7,8-dimethoxy-4-methyldibenzofuran-l-carboxaldehyde,named ligumedial (1) and 7,8-dimethoxy-4-methyldibenzofuran-l-carboxylic acid, named ligumcdiaoic acid (2), have been isolated from the underground parts of Ligularia intermedia.Their structures were clucidated by spectroscopic methods.
