Abstract:
OBJECTIVETo study the chemical constituents from Eremosparton songoricum.
METHODThe compounds were isolated with silica gel column chromatography and the structures of these compounds were elucidated by means of spectral analysis.
RESULTThe 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).
CONCLUSIONThese constituents were obtained from E. songoricum for the first time.
