Bercht. et Opiz., two new compounds together with five known triterpenoid saponins were isolated. The structures of the two new triterpenoid saponins, named cernuasides A and B, were elucidated as 3-O-[β-D-xylopyranosyl(1→2)]-[α-L-rhamnopyranosyl(1→4)]-α-Larabinopyranosyl hederagenin 28-O-β-D-glucopyranosyl ester (compound 1) and 3-O-[α-L-arabinopyranosyl(1→3)]-[α-L-rhamnopyranosyl (1→2)]-α-L-arabinopyranosyl hederagenin 28-O-β-D-glucopyranosyl ester (compound 2) by 1D, 2D-NMR techniques, ESIMS analysis, as well as chemical methods.
