| Abstract
| - Two new triterpenoid saponins, 3-O-[β-d-glucopyranosyl-(1→4)-β-d-glucopyranosyl-(1→4)-α-l-arabinopyranosyl]-hederagenin (1) and 3-O-[β-d-glucopyranosyl-(1→4)-β-d-glucopyranosyl-(1→4)-α-l-arabinopyranosyl]-hederagenin 28-O-[β-l-glucopyranosyl-(1→6)-β-l-glucopyranosyl] ester (2), together with fiveknown saponins, were isolated from an ethanolic extract of the tubers of Bongardia chrysogonum. Thestructures of 1 and 2 were determined on the basis of spectroscopic studies.
