【Abstract】 Objective: To study the chemical constituents from the leaves of Dalbergia hainanensis . Method: Compounds were isolated by chromatographic techniques on silica gel and polyamide column. Their structures were elucidated by chemical and spectroscopic methods. Results: Thirteen compounds were identified as 8-C-glucosylprunetin (1), 8-C-glucosylgenistein (2), 2-hydroxy-5-methoxy biochanin A (3), formononetin (4), 3,5-dimethoxy-4-hydroxybenzaldehyde (5), 1- O -β- D -glucopyranosyl-(2S, 3S, 4R, 8Z)-2-[(2R)-2-hydroxyl docosylamino]-8-octadecene-1, 3, 4-triol (6), friedelin (7), taxaxerol (8), 3(-hydroxy-glutin-5-ene (9), ursolic acid (10), β-sitosterol (11), daucosterol (12), lupeol (13). Conclusion: All the compounds were isolated from the plant for the first time.更多还原
