Abstract:
OBJECTIVETo study the chemical constituents from the leaves of Dalbergia hainanensis.
METHODCompounds were isolated by chromatographic techniques on silica gel and polyamide column. Their structures were elucidated by chemical and spectroscopic methods.
RESULTSThirteen 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).
CONCLUSIONAll the compounds were isolated from the plant for the first time.
