title: [Studies on the chemical constituents of Chinese herb Melastoma dodecandrum].
abstract: OBJECTIVE
  To investigate the chemical constituents of Chinese herb Melastoma dodecandrum.
  
  
  METHODS
  The chemical constituents were isolated by solvent extraction and chromatography. Their structure were identified on the basis of physic-chemical constants and specral data.
  
  
  RESULTS
  Five compounds were isolated and identified as hexacosanoic acid (I), quercetin(II), avicularin(III), gallic acid (IV), kaempferol(V).
  
  
  CONCLUSIONS
  The above-mentioned compounds were separated from the plant for the first time.
