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 as 6-O-[α-L-rhamnopyranosyl-(1-2)-β-D-glucopyranosyl]-dammara-3β,6β,12β,20(S),24ζ,25-hexaol (1).
