Abstract

A new dammarane-type saponin named quinquenoside L3 (1) together with vina-ginsenoside R3 (2) were isolated from the leaves and stems of Panax quinquefolium L. collected in Canada. On the basis of physicochemical and spectral evidences, 1 was established as 3-O-beta-D-glucopyranosyl-20-O-[beta-D-xylopyranosyl-(1-->6)-beta-D -glucopyranosyl] 20(S)-dammar-23-ene-3 beta, 12 beta,20,25-tetryol.
