title: Triterpenoid saponins from the root of Sideroxylon cubense.
abstract: Two triterpenoid saponins were isolated from the root of Sideroxylon cubense and their structures were established as 3-O-beta-D-glucopyranosyl-28-O-[alpha-L-rhamnopyranosyl(1-->3)- beta-D-xylopyranosyl(1-->4)-alpha-L-rhamnopyranosyl(1-->2) beta-D-xylopyranosyl] protobassic acid and 3-O-beta-D-glucopyranosyl protobassic acid. The first, designed as sideroxyloside A, is a new natural product.
