Three new minor dammarane saponins, quinquenosides L10 (1), L14 (2), and L16 (3), were isolated from the leaves and stems of Panax quinquefolium L. By the combination of one- and two-dimensional NMR techniques and MS spectroscopic analysis, their structures were established as 20-O-(alpha-L-arabinopyranosyl-(1-6)-O-beta-D-glucopyranosyl)-3-O-beta-D… CONTINUE READING
