摘要	Molecular diversity was generated by hydrolyzing the crude root saponins of Panax notoginseng (BURK.) F. H. CHFN under mild acidic condition (AcOH/EtOH 1 : 1). From the acid hydrolysate, five new dammarane glycosides, named notoginsenoside T-1 (=(3beta,6alpha,12beta,20E,23RS)-24,25-epoxy-6-[(beta-D-glueopyranosyl)oxy]dam mar-20(22) -ene-3,12,23-triol; 1), notoginsenoside T-2 (=(3beta,6alpha,12beta,20E,23RS)-24,25-epoxy-6-[(beta0-D-glucopyranosyl)oxy]-23-methoxydammar-20(22)-ene-3,12-diol 2), notoginsenoside T-3 (=(3beta, 6alpha,12beta 20S)-6-[(beta-D-glucopyranosyl)oxy]-20-etlioxydammar-24-ene-3,12-diol; 3), notoginsenoside T-4 (= (3beta,6alpha,12beta,20S,22E,24RS)-6-[(beta-D-glucopyranosyl)oxy]dammar-22-ene-3,12.20,24,25-pentol; 4), and notoginsenoside T-5 (=(3beta,6alpha,12beta, 24E)-6-[beta-D-xylopyranosyl-(1-->2)-beta-D-glueopyranosyl)oxy]dammara-20(21),24-diene-3,12-diol;5), were isolated, together with 15 known dammarane glycosides, and their structures were elucidated on the basis of spectroscopic evidence. Among the known compounds, ginsenosides Rg(3) and Rh-1 were isolated as major constituents, in addition to ginsenosides Rg(5) Rh-4, and a mixture of (20R)- and (20S)-25-hydroxyginsenoside Rh-1. all of which were obtained from P. notoginseng for the first time.
