title: [Study on chemical constituents from ethyl acetate extract of Myricaria bracteata].
abstract: OBJECTIVE
  To study the chemical constituents from the ethyl acetate extract of Myricaria bracteata.
  
  
  METHODS
  The chemical constituents were isolated and purified by chromatographic techniques, and their structures were identified by physical characters and spectroscopic analysis.
  
  
  RESULTS
  Sixteen compounds were isolated from the ethyl acetate portion of the 95% ethanolic extract of Myricaria bracteata, and identified as myricarin (1), myricarin B (2), 3alpha-hydroxytaraxer-14-en-28-oic acid (3), myricadiol (4), trans-ferulic acid 22-hydroxydocosanoic acid ester (5), docosyl-3, 4-dihydroxy-trans-cinnamate (6), dillenetin (7), 3, 5, 4'-trihydroxy-7-methoxyflavone (8), 3, 5, 4'-trihydroxy-7, 3'-dimethoxyflavone (9), methyl 3, 5-dihydroxy-4-methoxybenzoate (10), 3-hydroxy-4-methoxy cinnamic acid (11), sinapaldehyde (12), vanillin (13), syringaldehyde (14), 3, 3', 4'-trimethoxyellagic acid (15), methyl p-hyroxybenzoate (16).
  
  
  CONCLUSIONS
  Compounds 5, 6, 12-16 were isolated from the genus Myricaria for the fist time, all of the compounds were isolated from this plant for the fist time, except for 8 and 9.
