| 1 | 27-Ald-triterpenoid saponins from Adina rubella显示文摘Four new triterpenoid saponins were isolated from the roots of Adina rubella Hance. They were characterized as adinaic acid 3β-O-[α-L-rhamnopyranosyl(l→2)-β-D-glucopyranosyl(l→2)-β-D-glucurono-pyranoside-6-O-methyl ester]-28-O-β-D)-glucopyranoside, adinaic acid 3β-O-[α-L-rham-nopyranosyl(l→2)-β-D-glucopyranosyl(l→2)-β-D-glucuronopyranoside-6-O-butyl ester]-28-O-β-D-glu-copyranoside, adinaic acid 3β-O-[β-D-glucopyranosyl(l→2)-β-D-glucopyranosyl]-(28→1)-β-D-gluco-pyranosyl(l→6)-β-D-glucopyranosyl ester, 27-hydroxyursolic acid 3β-O-[α-L-rhamnopyranosyl (l→2)-β-O-glucopyranosyl(l→2)-β-D)-glucuronopyranoside-6-O-methyl ester]-28-O-β-D)-glucopyranoside. Their structures were elucidated by spectral methods, especially with the aid of 2D NMR techniques. Their complete assignments of the 1H and 13C NMR signals were carried out. | Fan, GJ He, ZS Wu, HM Xu, JF | 1997 | Chinese Journal of Chemistry1997，15，5： | 2 |
