| Abstract: | A new cycloartane bisdesmoside and two new trinorcycloartane glycosides, along with four known cycloartane compounds, were isolated from the rhizomes of Cimicifuga dahurica (Ranunculaceae). The structures of the new compounds were elucidated as 3-O-alpha-L-arabinopyranosyl cimigenol 15-O-beta-D-glucopyranoside, 24-hydroxy-12beta-acetoxy-25,26,27-trinorcycloartan-16,23-dione 3beta-O-alpha-L-arabinopyranoside, and 16alpha,24alpha-dihydroxy-12beta acetoxy-25,26,27-trinor-16,24-cyclocycloartan-23-one 3beta-O-alpha-L-arabinopyranoside by extensive NMR methods, FAB-MS, and hydrolysis. |
