Three new dammarane-type triterpenoid saponins, 1-3, were isolated and identified as (20S)-20-O-[β-D-xylopyranosyl-(1→6)-β-D- glucopyranosyl-(1→6)-β-D-glucopyranosyl]dammar-24-ene-3β, 6α,12β, 20-tetrol (1), (20S)-6-O-[(E)-but-2-enoyl-(1→6)-β- D-glucopyranosyl]dammar-24-ene-3β,6α,12β,20-tetrol (2), and (20S)-6-O-[β-D-xylopyranosyl-(1→2)-β-D-xylopyranosyl] dammar-24-ene-3β,6α,12β,20-tetrol (3) from the roots of Panax notoginseng (Burkill) F.H.Chen (Araliaceae). Their structures were elucidated on the basis of spectroscopic analyses, including 1D- and 2D-NMR techniques and HR-ESI-MS, as well as by acidic hydrolysis. Copyright
