title: Two new iridolactones and their glycosides from the roots of Patrinia scabra.
abstract: Investigation of the roots of Patrinia scabra afforded two new iridolactones, patriscabrol and isopatriscabrol. Their structures have been established by extensive analysis of their NMR spectra and an X-ray crystallographic analysis of patriscabrol. Four monoglucosides of each iridolactone were also isolated together with an apioside of glucosidic patriscabrol.
