Abstract:
Six new oleanane-type saponins, arilloside A-F (Ⅰ～Ⅵ), along with a known saponin, polygalasaponin ⅩⅩⅩⅤ(Ⅶ), were isolated from the root of Polygala arillata Buch.-Ham.. The structures of these new compounds were elucidated as 3-O-β-D-glucopyranosyl presenegenin 28-O-β-D-xylopyranosyl (1→4)-α-L-rhamnopyranosyl (1→2)-(3, 4-di-O-acetyl)-β-D-fucopyranoside(Ⅰ); 3-O-β-D-glucopyranosyl presenegenin 28-O-β-D-xylopyranosyl (1→3)-β-D-xylopyranosyl (1→4)-α-L-rhamnopyranosyl (1→2)-β-D-fucopyranoside(Ⅱ); 3-O-β-D-glucopyranosyl presenegenin 28-O-β-D-xylopyranosyl (1→3)-β-D-xylopyranosyl (1→4)-α-L-rhamnopyranosyl (1→2)-(3,4-di-O-acetyl)-β-D-fucopyranoside(Ⅲ); 3-O-β-D-glucopyranosyl presenegenin 28-O-β-D-xylopyranosyl (1→3)-[β-D-galactopyranosyl (1→4)]-β-D-β-D-xylopyranosyl (1→4)-α-L-rhamnopyranosyl (1→2)-β-D-fucopyranoside(Ⅳ); 3-O-β-D-glucopyranosyl presenegenin 28-O-β-D-xylopyranosyl (1→3)-[β-D-galactopyranosyl (1→4)]-β-D-xylopyranosyl (1→4)-α-L-rhamnopyranosyl (1→2)-(3-O-acetyl)-β-D-fucopyranoside(Ⅴ) and 3-O-β-D-glucopyranosyl presenegenin 28-O-β-D-xylopyranosyl (1→3)-[β-D-galactopyranosyl (1→4)]-β-D-xylopyranosyl (1→4)-α-L-rhamnopyranosyl (1→2)-(3,4-di-O-acetyl)-β-D-fucopyranoside(Ⅵ) on the basis of spectroscopic and chemical methods.
