Structures and stereochemistry of two sesquiterpene lactones from Ratibida columnifera which possess a new rearranged eudesmane derived carbon skeleton were deduced by NMR spectroscopy and X-ray diffraction.The main lactone fraction of this plant consisted of a family of unusual xanthanolides whose structures were established in the same manner.Other constituents included the new nerolidol derivative (3S*,5R*)-(-)-5-hydroxy-9-oxonerolidol.
