Objective: To study the chemical constituents from Eremosparton songoricum. Method: The compounds were isolated with silica gel column chromatography and the structures of these compounds were elucidated by means of spectral analysis. Result: The seven compounds were identified as: 5, 7, 4'-trihydroxyflavone (apigenin) (I), 5-hydroxy-7, 4'-dimethoxyflavone (II), 5,7-dibydroxy-3', 4'-dimethoxyflavone (III), 5,7-dihydroxy-4'-methoxyflavone (acacetin) (IV), 5,7,4'-trihydroxy-3'-methoxy flavone (chrysoeriol) (V), 5,6, 3',4'-tetrahydroxy-7-methoxyflavone (pedalitin) (VI) and 5,4'-dihyroxy-7,3'-dimethoxy flavone-4'-O-D-glucoside (flavogadorinin) (VII). Conclusion: These constituents were obtained from E. songoricum for the first time.
