摘要：

Two new triterpenoid saponins, beciumecine I 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-rhamnopyranosyl( 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.
