Description:
Three new dammarane-type triterpenoid saponins, 1 – 3 , were isolated and identified as (20 S )-20- O -[ β - D -xylopyranosyl-(1→6)- β - D -glucopyranosyl-(1→6)- β - D -glucopyranosyl]dammar-24-ene-3 β ,6 α ,12 β , 20-tetrol ( 1 ), (20 S )-6- O -[( E )-but-2-enoyl-(1→6)- β - D -glucopyranosyl]dammar-24-ene-3 β ,6 α ,12 β ,20-tetrol ( 2 ), and (20 S )-6- O -[ β - D -xylopyranosyl-(1→2)- β - D -xylopyranosyl]dammar-24-ene-3 β ,6 α ,12 β ,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.
