Two new triterpenoid saponins, brachyposide A (1) {3-O-β-D-galactopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-glucuronopyranosyl-2β,3β,16α,23-tetrahydroxyolean-12-en-28-oic acid 28-O-β-D-apiofuranosyl-(1→3)-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl ester} and brachyposide B (2) {3-O-β-D-glucopyranosyl-(1→3)-β-D-galactopyranosyl-(1→3)-β-D-glucuronopyranosyl-2β,3β,23-trihydroxyolean-12-en-28-oic acid 28-O-β-D-xylopyranosyl-(1→4)-[β-D-apiofuranosyl-(1→3)]-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl ester}, together with four known triterpenoid saponins, including tabguticoside A, nipponoside D, palmatoside E and ciwujianoside A1, were isolated from the stem bark of Acanthopanax brachypus. Their structures were elucidated on the basis of spectroscopic and chemical evidence.
