Two new iridolactones and their glycosides from the roots of Patrinia scabra

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...

Zusammenfassung:	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.
