| Abstract
|
| [Objective] To investigate the chemical components of the herb Tribulus terrestris L. [Methods] The chemical components were isolated through column chromatography on macroporous resin (SP825), silica gel, octadecyl silica (ODS) columns and PHPLC. Their structures were identified by physicochemical properties and spectra data. [Results] Five steroidal saponins were obtained from Tribulus terrestris L. They were uttroside B (1), polianthoside (2), tigogenin-3-O-β-D-xylopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-glucopyranosyl-(1→4)-[α-L-rhamnopyranosyl-(1→2)]-β-D-galactopyranoside (3), (25R)-26-O-β-D-glucopyranosyl-5α-furost-12-one-3β, 22α, 26-triol-3-O-β-D-gluco-pyranosyl-(1→4)-β-D-galactopyranoside (4) and hecogenin-3-O-β-D-glucopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside (5). [Conclusion] Compounds 1 and 2 were obtained from Tribulus terrestris L. for the first time. |
