title: [Chemical constituents of Acacia catechu].
abstract: OBJECTIVE
  To study the chemical constituents of Chinese medicine Acacia catechu.
  
  
  METHODS
  Isolation and purification were carried out on normal phase silica gel, Sephadex LH-20, ODS column chromatography etc. Constituents were identified by physicochemical properties and spectral analysis.
  
  
  RESULTS
  Twelve compounds were identified as 4-hydroxybenzoic acid( 1), kaempferol (2), quercetin (3), 3,4',7-trihydroxyl-3', 5-dimethoxyflavone (4), catechin (5), epicatechin (6), afzelechin (7), epiafzelechin (8), mesquitol(9), ophioglonin (10), aromadendrin (11), and phenol (12).
  
  
  CONCLUSIONS
  Compounds 7, 12 were isolated from A. catechu for the first time, and compounds 4, 9-11 were isolated from the genus Acacia for the first time.
