Abstract

Nine new oleanane-type saponins, polygalasaponins XXXIII--XLI, along with seven known saponins were isolated from the roots of Polygala fallax HEMSL. Polygalasaponins XXXIII-XLI were elucidated as 3-O-beta-D-glucopyranosyl presenegenin 28-O-beta-D-xylopyranosyl-(1-->4)-alpha-L-rhamnopyranosyl- (1-->2)-(4-O-acetyl)-beta-D-fuco-pyranosyl ester, 3-O-beta-D-glucopyranosyl presenegenin 28-O-beta-D-galactopyranosyl-(1-->4)-beta-D-xylopyranosyl- (1-->4)-alpha-L-rhamnopyranosyl-(1-->2)-(4-O-acetyl)-beta-D- fucopyranosyl ester, 3-O-beta-D-glucopyranosyl presenegenin 28-O-beta-D-galactopyranosyl-(1-->4)-beta-D-xylopyranosyl-(1-->4)- alpha-L-rhamnopyranosyl-(1-->2)-(3,4-di-O-acetyl)-beta-D-fucopyranosyl ester, 3-O-beta-D-glucopyranosyl presenegenin 28-O-beta-D-galactopyranosyl-(1-->4)-beta-D-xylopyranosyl-(1-->4)- [(5-O-acetyl)-beta-D-apiofuranosyl-(1-->3)]-alpha-L-rhamnopyranosy l- (1-->2)-(3,4-di-O-acetyl)-beta-D-fucopyranosyl ester, 3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl presenegenin 28-O-beta-D-xylopyranosyl-(1-->4)-alpha-L-rhamnopyranosyl-(1-->2)- (3-O-acetyl)-beta-D-fucopyranosyl ester, 3-O-beta-D-glucopyranosyl- (1-->2)-beta-D-glucopyranosyl presenegenin 28-O-beta-D-galactopyranosyl-(1-->4)-beta-D-xylopyranosyl- (1-->4)-alpha-L-rhamnopyranosyl-(1-->2)-(4-O-acetyl)-beta-D- fucopyranosyl ester, 3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl presenegenin 28-O-beta-D-xylopyranosyl-(1-->4)-alpha-L-rhamnopyranosyl-(1-->2)- [alpha-L-rhamnopyranosyl-(1-->3)]-(4-O-acetyl)-beta-D-fucopyranosyl ester, 3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl presenegenin 28-O-beta-D-galactopyranosyl-(1-->4)-beta-D-xylopyranosyl-(1-->4)- [beta-D-apiofuranosyl-(1-->3)]-alpha-L-rhamnopyranosyl-(1-->2)- (3,4-di-O-acetyl)-beta-D-fucopyranosyl ester and 3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl presenegenin 28-O-beta-D-galactopyranosyl-(1-->4)-beta-D-xylopyranosyl-(1-->4)- [(5-O-acetyl)-beta-D-apiofuranosyl-(-->3)]-alpha-L-rhamnopyranosyl - (1-->2)-(3,4-di-O-acetyl)-beta-D-fucopyranosyl ester, respectively, on the basis of spectroscopic and chemical evidence.

摘要
