Abstract: Two minor saponins were isolated from the leaves of P. ginseng and their struc-tures were elucidated as 3β, 12β, 20(S)-trihydroxyl-dammar-24 (25)-ene-(20-O-α-L-arabinofurano-syl (1→6)-β-D-glucopyranosyl)-3-O-β-D-glucopyranoside (1), and 3β, 12β, 20(S)-trihydroxyl-dam-mar-24 (25)-ene-(20-O-α-L-arabinopyranosyl (1→6)-β-D-glucopyranosyl)-3-O-β-glucopyranoside (2), respectively The fonner corresponds to notoginsenoside-Fe which is isolated for the first time from the title plant The latter is a new natural product and named as ginsenoside-Rd2.

Key words: Notoginsenoside-Fe, Ginsenoside-Rd2
