To study the chemical constituents with antiviral action from Yinqiaosan on influenza virus. Constituents were isolated by different kinds of column chromatography and their structures were elucidated with chemical and spectral methods. Eleven chemical constituents were isolated and elucidated as arctiin, phillyrin, forsythiaside, liquiritigenin, liquiritin, genistein, formononetin, daidzein, glycitrin, 3,3',4-tri-omethlellagic acid and chlorogenic acid. Genistein, daidzein, glycitrin and 3,3',4-tri-omethlellagic acid were isolated from Yinqiaosan for the first time.
