[Chemical constituents from the leaves of Dalbergia hainanensis].
OBJECTIVE
To study the chemical constituents from the leaves of Dalbergia hainanensis.


METHODS
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-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).


CONCLUSIONS
All the compounds were isolated from the plant for the first time.
