Two new triterpenoid saponins, beciumecine 1 and 2, were isolated from the root bark of Becium grandiflorum var. obovatum and their structures established as 3-O-(β-D-glucopyranosyl) terminolic acid 28-O-β-D- apiofuranosyl(1-3)-[α-L-rhamnopyranosyl(1-3)-β-D-xylopyranosyl(1-4)]-α-L- rhamnopyranosyl(1-2)-α-L-arabinopyranoside and 3-O-(β-D-glucopyranosyl) 24- hydroxyterminolic acid 28-O-α-L-rhamnopyranosyl(1-3)-β-D-xylopyranosyl(1- 4)-α-L-rhamnopyranosyl(1-2)-α-L-arabinopyranoside, respectively.
