This work reports the isolation and characterization of three saponins, including a new one (3), from an n-BuOH extract of the root of . Ferula hermonis Boiss. Their structures (1-3) were elucidated on the basis of spectroscopic evidence using 1D and 2D-NMR data, high resolution MS and chemical methods and identified as 3ß-O-ß-D-glucopyranosyl-(1→2)-ß-D-galactopyranosyl-(1→2)-ß-D-glucuronopyranosyl-oleanolic acid (Sandrosaponin X, . 1), 3. ß- O- ß-D-glucopyranosyl-(1→2)- ß-D-galactopyranosyl-(1→2)- ß-D-glucuronopyranosyl-oleanolic acid 28- O- ß-D-glucopyranoside (Sandrosaponin IX, . 2) and 3. ß- O- ß-D-glucopyranosyl-(1→2) ß-D-galactopyranosyl-(1→2)- ß-D-glucuronopyranosyl-oleanolic acid-28- O ß-D-glucopyranoside methyl ester (Sandrosaponin XI, . 3). The chemotaxonomic significance of these compounds was summarized.
- Ferula hermonis
- Triterpenoid saponins
