title: [Chemical constituents from the leaves of Dalbergia hainanensis].
abstract: 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.
