摘要

To investigate the chemical constituents of Fraxinus paxiana.The chemical constituents were isolated and purified by chromatographic techniques and the structures of the compounds were identified with or by spectroscopic methods.Fifteen compounds were obtained from the methanol extract of F. paxiana and their structures were elucidated as esculin (1), esculetin (2), fraxin (3), fraxetin (4), salidroside (5), osmanthuside H (6), liriodendrin (7), 3-(4-beta-D-glucopyranosyloxy-3-methoxy)-phenyl-2E-propenol (8), threo-syringylglycerol (9), euscaphic acid (10), 3-hydroxy-1-(4-hydroxy-3, 5-dimethoxyphenyl)-1-propanone (11), omega-hydroxypropioguaiacone (12), sinapyladehyde (13), betulinic acid (14) and mannitol (15).All compounds were obtained from this plant for the first time.
