  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-(beta-D-glucopyranosyl) terminolic acid 28-O-beta-D-apiofuranosyl(1-3)-[alpha-L-rhamnopy-anosyl (1-3)-beta-D-xylopyranosyl(1-4)]-alpha-L-rhamnopyranosyl (1-2)-alpha-L-arabinopyranoside and 3-O-(beta-D-glucopyranosyl) 24-hydroxyterminolic acid 28-O-alpha-L-rhamnopyranosyl(1-3)-beta-D-xylopyranosyl(1-4)-alpha-L- rhamnopyranosyl(1-2)-alpha-L-arabinopyranoside, respectively.
