title: [Chemical Constitutes from Seeds of Plantago asiatica].
abstract: OBJECTIVE
  To study the chemical constituents of Plantago asiatica seeds.
  
  
  METHODS
  The constituents were isolated from the seeds of Plantago asiatica by column chromatography over silica gel, MCI gel, macroporous resin HP-20, Sephadex LH-20, Polyamide and by preparative HPLC. Their structures were elucidated by analysis of physical and chemical properties and spectral data.
  
  
  RESULTS
  Five compounds were isolated and their structures were identified as acteoside (1), isoacteoside (2), decaffeoylacteoside (3), tetradecanoic acid (4), and bis (2-ethythexyl) benzene-1,2-dicarboxylate (5).
  
  
  CONCLUSIONS
  Compound 5 is isolated from Plantaginaceae for the first time. Compounds 3 and 4 are firstly characterized in Plantago asiatica.
