The invention discloses a method for extracting total flavonoids from the lespedeza hedysaroides of pasture, purifying the total flavonoids and separating monomers. In the method, the entire lespedeza hedysaroides is cleaned, dried, ground, added with ethanol and heated for refluxing extraction; an extracting solution is concentrated into a dilute alcoholic solution; a petroleum ether extraction method is used for eliminating chlorophyll; decompression-concentration is carried out to the solution after extraction and residual alcohol is removed, after that, acetic ether and n-butyl alcohol are used for extraction in sequence; a solvent is recycled; ethanol dissolves, and decompression-concentration and spray drying are carried out, thus obtaining a lespedeza hedysaroides extract which respectively goes through a normal-phase silicagel column and a polyamide column; an obtained yellow precipitate is the total flavonoids of the lespedeza hedysaroides; the separation of monomeric compounds is carried out to the total flavonoids; a mass spectrograph and a nuclear magnetic resonance chromatogram are used for carrying out verification and finding out the structure is respectively orientin, homo-orientin, agnuside, isovitexin, iso-myricitrin and quercetin-3-O- glucoside. The method has simple procedure, reasonable design, high extracting efficiency and high purity of obtained products, thus bieng beneficial to industrialized production.
