Quinquenoside L9 from leaves and stems of Panax quinquefolium L.
During additional chemical investigation on the saponin composition of leaves and stems of Panax quinquefolium L, a new minor dammarane saponin, quinquenoside L9 (1) has been obtained. By means of physico-chemical evidences and spectral analysis, its structure was elucidated 6-O-[alpha-L-rhamnopyranosyl-(1-2)-beta-D-glucopyranosyl]-dammara-3beta, 6beta,12beta,20(S),24zeta,25-hexaol (1).
