Abstract:
Objective: To study the chemical constituents from the leaves of Nitraria tangutorum. Methods: The chemical constituents were isolated by solvent extraction, repeated silica gel chromatography, and preparative-HPLC. Their structures were elucidated by physicochemical properties and 1H-NMR and 13C-NMR data. Results: Nine compounds were isolated from the ethanol extract of the leaves of N. tangutorum and their structures were identified as 4-oxo-β-ionol β-D-glycopyranoside (1), (6R,9R)-3- oxo-α-ionol β-D-glycopyranoside (2), blumenyl C β-D-glucopyranoside (3), blumenyl A β-D-glucopyranoside (4), syringaresinol- 4'- O-β-D-glucopyranoside (5), citrusin B (6), nikoenoside (7), 2-phenylethyl-β-D-glucopyranoside (8) and indole-3-ethyl-β- D-glucopyranoside (9). Conclusion: All the isolates are reported from the plants of Nitraria L. for the first time and the 13C-NMR data of compound 9 are also reported for the first time.
