✦ Synopsis
Five new triterpene saponins 1 ± 5 were isolated from the roots of Muraltia ononidifolia E. Mey along with the two known saponins 3
arabinopyranosyl] ester (medicagenic acid (4a,2b,3b)-2,3-dihydroxyolean-12-ene-23,28-dioic acid). Their structures were elucidated mainly by spectroscopic experiments, including 2D-NMR techniques, as 3-O-(b-d-glucopyranosyl)medicagenic acid 28-[O-bd-apiofuranosyl-(1 3 3)-O-b-d-xylopyranosyl-(1 3 4)-O-a-l-rhamnopyranosyl-(1 3 2)-a-l-arabinopyranosyl] ester (1), 3-O-(b-d-glucopyranosyl)medicagenic acid 28-{[O-b-d-xylopyranosyl-(1 3 4)-O-[b-d-apiofuranosyl-(1 3 3)]-O-a-l-rhamnopyranosyl-(1 3 2)-a-l-arabinopyranosyl} ester (2), 3-O-[O-b-d-glucopyranosyl-(1 3 2)-b-d-glucopyranosyl]medicagenic acid 28-
