摘要：
Four new cycloartane glycosides were isolated from the aerial parts of Thalictrum fortunei (Ranunculaceae). The chemical structures of these new glycosides were elucidated as 3-O-beta-o-glucopyranosyl-(1 -> 4)-beta-D-fucopyranosyl (22S,24Z)-cycloart-24-en-3 beta,22,26-triol 26-O-beta-D-glucopyranoside, 3-O-beta-D-glucopyranosyl-(1 -> 4)-beta-D-fucopyranosyl (22S,24Z)-cycloart-24-en-3 beta,22,26-triol 26-O-beta-D-quinovopyranosyl-(1 -> 6)-beta-D-glucopyranoside, 3-O-beta-D-glucopyranosyl-(1 -> 4)-beta-D-fucopyranosyl (22S,24Z)-cycloart-24-en-beta,22,26-triol 26-O-beta-D-xylopyranosyl(1 -> 6)-beta-D-glucopyranoside, and 3-O-beta-o-glucopyranosyl-(1 -> 4)-beta-D-fucopyranosyl (22S,24Z)-cycloart-24-en-3 beta,22,26-triol 26-O-alpha-L-arabinopyranosyl-(1 -> 6)-beta-D-glucopyranoside by extensive NMR methods, HR-ESI-MS, and hydrolysis. This is the first report of (22S,24Z)-3 beta,22,26-trihydroxycycloartan-24-ene (thelictogenin A, 5) 14 being glycosylated at C-26.
