Investigation of the roots of Patrinia scabra afforded two new iridola
ctones, patriscabrol and isopatriscabrol. Their structures have been e
stablished by extensive analysis of their NMR spectra and an X-ray cry
stallographic analysis of patriscabrol. Four monoglucosides of each ir
idolactone were also isolated together with an apioside of glucosidic
patriscabrol.
