摘要：

Three new oleanane-type triterpene saponins (1, 2 and 3) were isolated from aerial parts of Gladiolus gandavensis, along with two known compounds (4 and 5). Their structures were elucidated as 29-O-(beta-D-glucopyranosyl)-2 beta,3 beta-dihydroxyolean-12-en-28-oicacid(1), 3-O-(beta-D-xylopyranosyl)-29-O-(beta-D-glucopyranosyl)-12-en-28-oic acid (2), and 2 beta,3 beta,29-trihydroxyolean-12-en-28-oic acid 28-O-[beta-D-glucopyranosyl(1 -> 2)-(alpha-L-rhamnopyranosyl(1 -> 6))-beta-D-glucopyranosyl] ester (3), by spectroscopic methods, and by comparison with known analogues. These oleanane-type triterpene saponins glycosidated at C-29 were not obtained frequently.
