title: [Studies on the flavonoid constituents in herb of Eremosparton songoricum].
abstract: OBJECTIVE
  To study the chemical constituents from Eremosparton songoricum.
  
  
  METHODS
  The compounds were isolated with silica gel column chromatography and the structures of these compounds were elucidated by means of spectral analysis.
  
  
  RESULTS
  The seven compounds were identified as: 5,7,4'-trihydroxyflavone (apigenin) (I), 5-hydroxy-7,4'-dimethoxyflavone (II), 5,7-dihydroxy-3',4'-dimethoxyflavone (III), 5,7-dihydroxy-4'-methoxyflavone (acacetin) (IV), 5,7,4'-trihydroxy-3'-methoxyflavone (chrysoeriol) (V), 5,6,3',4'-tetrahydroxy-7-methoxyflavone (pedalitin) (VI) and 5,4'-dihydroxy-7,3'-dimethoxyflavone-4'-O-D-glucoside (flavogadorinin) (VII).
  
  
  CONCLUSIONS
  These constituents were obtained from E. songoricum for the first time.
