Y. Lang. By means of spectral and chemical analysis, the structure of the new compounds were established as neotigogenin-3-O-(-D-glucopyranosyl (1?3)-(-D-xylopyranosyl-(1?3)-[(-D-glucopyranosyl(1?2)]-(-D-glucopyranosyl(1?4)-(-D-galactopyranoside (1) and neotigogenin-3-O-(-D-glucopyranosyl(1?3)-(-D-glucopyranosyl (1?3)-(-D-xylopyranosyl(1?3)-[(-D-glucopyranosyl(1?2)]-(-D-glucopyranosyl(1?4)-(-D-galactopyranoside (2) respectively.展开更多
