|Further studies on dammarane-saponins of Sanchi-Ginseng[Reference: WebLink]|
|Three new saponins, named notoginsenosides-R3 (11), -R4 (12), and -R6 (13) were isolated from Sanchi-Ginseng, roots of Panax notoginseng. The structures of these saponins were established as 20 (S)-protopanaxatriol 6-O-β-D-glucopyranosyl-20-O-β-D-glucopyranosyl (1→6)-β-D-glucopyranoside (11), 20 (S)-protopanaxadiol 3- [O-β-D-glucopyranosyl (1→2)-β-D-glucopyranosyl]-20-O-β-D-xylopyranosyl (1→6)-β-D-glucopyranosyl (1→6)-β-D-glucopyranoside (12), and 20 (S)-protopanaxatriol 6-O-β-D-glucopyranosyl-20-O-α-D-glucopyranosyl (1→6)-β-D-glucopyranoside (13), respectively. Besides these saponins, two known saponins, 20-O-Glucoginsenoside Rf (9) and gypenoside XVII (10), were also isolated and identified. From corms of this plant, ginsenosides-Rb1 (1), -Rb2 (26), -Rd (2), -Re (3), -Rg1 (4), and notoginsenoside-R1 (5) were isolated in relatively high yields.
