title: Two new benzofurans and other constituents from Ligularia przewalskii.
abstract: Two new benzofurans, 2-(1,2-dihydroxyisopropyl)-5,6-dimethoxybenzofuran (1) and 2-(1-O-feruloyl-2-hydroxyisopropyl)-5,6-dimethoxybenzofuran (2), along with eleven known compounds (3-13) were isolated from the roots of Ligularia przewalskii. Their structures were established on the basis of spectroscopic methods. The antibacterial activity of compounds 1 and 3-5 was tested.
