    Journal: Zhongguo Zhong Yao Za Zhi; 2005 Jan; 30(2):126-8. PubMed ID: 15714817.
    Abstract:
    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-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). CONCLUSION: These constituents were obtained from E. songoricum for the first time.
