Two saponins were isolated from the leaves of Lippia alba. Their structures were established using one- and two-dimensional NMR spectroscopy and mass spectrometry. These new compounds were elucidated as 3-O-β-D-glucopyranosyl-28-O-(α-L-rhamnopyranosyl-(1?3)-β-D-xylopyranosyl-(1?4)-α-L-rhamnopyranosyl-(1?2)-α-L-arabinopyranosyl)-16α,23-dihydroxy-olean-12-en-28-oic acid, named as Lippiasaponin I (2) and as 3-O-β-D-glucopyranosyl-28-O-(α-L-rhamnopyranosyl-(1?3)-β-D-xylopyranosyl-(1?4)-α-L-rhamnopyranosyl-(1?3)-α-L-arabinopyranosyl)-16α,23-dihydroxy-olean-12-en-28-oic acid, named Lippiasaponin II (3).
