Article abstract of DOI:10.1016/0031-9422(91)83648-5

Two new saponins were isolated from Mimosa tenuiflora and their structures established as 3-O-<<(α-L-rhamnopyranosyl(1->2)-β-D-glucopyranosyl-(1->3))-(α-L-arabinopyranosyl-(1->4))-β-D-xylopyranosyl-(1->2)>-<β-D-xylopyranosyl-(1->4)>-β-D-glucopyranosyl>-28-O-α-L-rhamnopyranosyl oleanolic acid and 3-O-<<(α-L-rhamnopyranosyl-(1->2)-β-D-glucopyranosyl-(1->3))-(α-L-arabinopyranosyl-(1->4))-β-D-xylopyranosyl-(1->2)>-<β-D-xylopyranosyl-(1->4)>-β-D-glucopyranosyl> oleanolic acid.
