On the basis of spectroscopic analysis, including HR-ESI-MS, IR, 1D, and 2D NMR spectral data and hydrolysis followed by chromatographic analysis, the structure of the new triterpenoid saponin was elucidated as 3-O-α-L-rhamnopyranosyl-(1 → 6)-β-D-glucopyranosyl-(1 → 4)-β-D-glucopyranosyl-(1 → 4)-β-D-ribopyranosyl-(1 → 3)-α-L-rhamnopyranosyl-(1 → 2)-α-L-arabinopyranosyl oleanolic acid 28-O-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranoside.
