摘要	Six new triterpenoid glycosides, gynosaponins I-VI (1-6, resp.), together with three known compounds, ginseng Rb(1) (7), gypenoside XLIX (8), and gylongiposide I (9), were isolated from the aerial parts of Gynostemma pentaphyllun. Based on ESI-MS, IR, 1D- and 2D-NMR data (HMQC, HMBC, COSY, and TOCSY), the structures of the new compounds were determined as (3 beta,12 beta,20S)-trihydroxydammar-24-ene 20-O-[alpha-rhamnopyranosyl-(1 -> 2)]-beta-glucopyranoside (1), (3 beta,12 beta,20S)-trihydroxydammar-24-ene 20-O-[alpha-rhamnopyranosyl-(1 -> 2)]-alpha-rhamnopyranoside-(1 -> 3)]-beta-glucopyranoside (2), (3 beta,12 beta,20S)-trihydroxydammar-24-ene 3-O-beta-glucopyranosyl-20-O-[alpha-rhamnopyranosyl- 1 -> 2)]-beta-glucopyranoside (3), (3 beta,12 beta,20S)-trihydroxydammar-24-ene 3-O-beta-glucopyranosyl-20-O-[alpha-rhamnopyransoyl-(1 -> 2)][alpha-rhamnopyranosyl-(1 -> 3)]-beta-glucopyranoside (4), (3 beta,12 beta,20S)-trihydroxydammar-24-ene 3-O-{[beta-glucopyranosyl-(1 -> 2)]-beta-glucopyranosyl}-20-O-[alpha-rhamnopyranosyl-(1 -> 2)]-beta-glucopyranoside (5), and (3 beta,12 beta,20S)-trihydroxydammar-24-ene 3-O-{[beta-glucopyranosyl- (1 -> 2)-beta-glucopyranosyl}-20-O-[alpha-rhamnopyransyl-(1 -> 2)][(alpha-rhamnopyranosyl-(1 -> 3)]-beta-glucopyranoside (6).
