| 摘 要： | Three new 27-nor-triterpenoid saponias named rubenorside A (1),rubenorside B(2) and rubenorside C (3) were isolated from the roots of Adina rubella.Their structures were characienzed as pyrocincholic acid 3β-O-α-L-rhamnopyranosyl(28→1 )-β-D-glucopyranosyl ester (1),pyrocinchohe acid 3β-O-β-D-glucopyranosyl(1→2)-β-D-fucopyranosyl(28→1)-β-D-glucopyranosyl(1→6)-β-D-glico-pyranosyl ester (2) and pyrocincholic acid 3β-O-β-D-glucopyranosyl(1→2)-β-D-glucopyranosyl(28→1)β-D-glucopyranosyl(1→6)-β-D-glucopyranosyl ester () by spectral methods,especially 2D NMR experiments.

| Abstract: | Three new 27-nor-triterpenoid saponins named rubenorside A (l), rubenorside B (2) and rubenorside C (9) were isolated from the roots of Adina rubella. Their structures were characterized as pyrocincholic acid 3β-O-α-L-rhamnopyranosyl(28→ 1)-β-D-glucopyranosyl ester (1), pyrocincholic acid 3β-O-β-D-glucopyranosyl(1→2)-β-D-fucopyranosyl(28→1)-β-D-glucopyranosyl(1→6)-β-D-glucopyranosyl ester (2) and pyrocincholic acid 3β-O-β-D-glucopyranosyl(1→2)-β-D-glucopyranosyl (28→ 1)-β-D-glucopyranosyl( 1→6)-β-D-glucopyranosyl ester (S) by spectral methods, especially 2D NMR experiments. |
