| 摘 要： | 从金铁锁（Psammosilene tunicoides W.C.Wu et C.Y.Wu)根部分离得到5个齐墩果烷型五环三萜皂苷，它们的结构通过波谱和化学方法分别鉴定为：3-O-β-D-galactopyranosyl-(1→2)-β-D-glucuronopyranosyl-gypsogenin(1),3-O-β-D-galactopyranosyl-(1→2)-β-D-galactopyranosyl-(1→3)-β-D-glucuronopyranosyl-gypsogenin(2),3-O-β-D-galactopyranosyl-(1→2)-β-D-glucuronopyra-nosyl-gypsogenin-28-O-β-D-xylopyranosyl-(1→4)-β-D-glucopyranosyl-(1→3)]-α-L-rhamnopyranosyl(1→2)-β-D-fucopyranoside(LobatosideI,3),3-O-β-D-galactopyranosyl-(1→2)-β-D-xylopyranosyl-(1→3)-β-D-glucuronopyranosylgypsogenin-28-O-β-D-xylopyranosyl-(1→4)-β-D-glucopyranosyl-(1→3)]-α-L-rhamnopyranosyl(1→2)-β-D-fucopyranoside(4),3-O-β-D-galactopyranosyl-(1→）-β-D-glucuro-nopyranosyl-grpsogenin-28-O-β-D-xylopyranosyl-(1→4)-β-D-6-O-acetylglucopyranosyl-(1→3)-β-D-glucuro-nopyranosyl-gypsogenin-28-O-β-D-xylopyranosyl-(1→4)-β-D-6-O-acetylglucopyranosyl-(1→3)]-α-L-rh-amnopyranosyl(1→2)-β-D-fucopyranoside(5)，其中5为新化合物，1和2为首次从自然界中分离得到。

| Abstract: | Five oleanane-type triterpenoid saponins were isolated from the roots of Psammosilene tunicoides W.C.Wu et C.Y.Wu. Their structures were elucidated by spectral and chemical methods as 3-O-β-D-galactopyranosyl-(1→2)-β-D-glucuronopyranosyl-gypsogenin(1),3-O-β-D-galactopyranosyl-(1→2)-β-D-xylopyranosyl-(1→3)]-β-D-glucuronopyranosyl-gypsogenin(2), 3-O-β-D-galactopyranosyl-(1→2)-β-D-glucuronopyranosyl-gypsogenin-28-O-β-D-xylopyranosyl-(1→4)-β-D-glucopyranosyl-(1→3)]-(-L-rhamnopyranosyl(1→2)-β-D-fucopyranoside(Lobatoside I,3),3-O-β-D-galactopyranosyl-(1→2)-β-D-xylopyranosyl -(1→3)]-β-D-glucuronopyranosyl-gypsogenin-28-O-β-D-xylopyranosyl-(1→4)-β-D-glucopyranosyl-(1→3)]-α-L-rhamnopyranosyl(1→2)-β-D-fucopyranoside (4),3-O-β-D-galactopyranosyl-(1→2)-β-D-glucuronopyranosyl-gypsogenin-28-O-β-D-xylopyranosyl-(1→4)-β-D-6-O-acetyl- glucopyranosyl-(1→3)]-α-L-rhamnopyranosyl(1→2)-β-D-fucopyranoside (5). Among them, compound 5 was a new triterpenoid saponin. |
