Fig. 1: Structural and compositional variations in triterpenoid saponins among Panax and Aralia genera.

a Structures of different types of triterpene saponins isolated from A. elata, P. ginseng, and P. notoginseng. Glc D-glucopyranosyl, GlcA D-glucuronopyranosyl, Gal D-galactopyranosyl, Ara(p) L-arabinopyranosyl, Ara(f) L-arabinofuranosyl, Rha L-rhamnopyranosyl, Xyl D-xylopyranosyl. b Compositional variations in saponins with different triterpene skeletons in A. elata, P. ginseng, and P. notoginseng. The major triterpene profiles from a mixture of leaves, stems, and roots were determined using LC–MS. Source data underlying b are provided as a Source Data file.
