[Chemical constituents from the leaves of Dalbergia hainanensis].Zhongguo Zhong Yao Za Zhi. 2003 Jun; 28(6):527-30.ZZ
To study the chemical constituents from the leaves of Dalbergia hainanensis.
Compounds were isolated by chromatographic techniques on silica gel and polyamide column. Their structures were elucidated by chemical and spectroscopic methods.
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).
All the compounds were isolated from the plant for the first time.
