Chemical constituents from the leaves of Dalbergia hainanensis / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents from the leaves of Dalbergia hainanensis.</p><p><b>METHOD</b>Compounds were isolated by chromatographic techniques on silica gel and polyamide column. Their structures were elucidated by chemical and spectroscopic methods.</p><p><b>RESULTS</b>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-beta-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), beta-sitosterol (11), daucosterol (12), lupeol (13).</p><p><b>CONCLUSION</b>All the compounds were isolated from the plant for the first time.</p>
