title: [Chemical constituents from Embelia laeta].
abstract: OBJECTIVE
  To study the chemical constituents from Embelia laeta.
  
  
  METHODS
  The constituents from the EtOAc fraction of ethanol extract of Embelia laeta were separated and purified by column chromatography with silica gel and polyamide. The compounds were identified by their physiochemical proerties and spectral data.
  
  
  RESULTS
  Eleven compounds were isolated and identified as p-sitosterol (1), beta-daucosterel (2), gallic acid (3), vanillic acid (4), rutin (5), hyperin (6), quercetin (7), kaemperol ( 8), chrysoeriol (9), physcion(10) and apigenin-7-O-glucoside(ll).
  
  
  CONCLUSIONS
  Compounds 5-11 are isolated from this genus for the first time.
