Objective:To study the chemical constituents of total flavones from Epimedium Herb for anti senile dementia. Methods:The total flavones from Epimedium herb were isolated and repeatedly purified by analytical and preparative HPLC,they were identified and structurally elucidated by spectral analysis. Results:Four compounds were obtained. They were identified as Epimedoside A,Epimedoside B,Epimedoside C,Icariin. Conclusion: Epimedoside A,Epimedoside B,Epimedoside C and Icariin were the mostly components of total flavones from Epimedium herb for antisenile dementia.
