title: Two minor benzofuranosesquiterpene dimers from Ligularia virgaurea.
abstract: From the roots of Ligularia virgaurea, two new benzofuranosesquiterpene dimers, named virgaurin B and virgaurin C, have been isolated. Their structures have been elucidated from the interpretation of the 1H-, 13C-NMR, mass and IR spectral data.
