摘要：

Three triterpenoid saponins were isolated from the bark of Xeromphis nilotica (Rubiaceae). Their structures were established by spectroscopic methods (C-13-NMR, H-1-NMR and MS) and chemical methods (acetylation, permethylation, acidic and basic hydrolysis). They were identified as : beta-D-glucopyranosyl-(1-->3) quinovic acid, 3-0-[0-beta-D-glucopyranosyl-(1-->4)-beta-D-glucopyranosyl] pomolic aicd, and 3-0-[0-alpha-L-rhanino-pyranosyl-(1-->2) - 0-beta-D-glucopyranosyl-(1-->2) - beta-D-gluco-pyranosyl] oleanolic acid.
