The invention discloses a method for determining the content of calycosin-7-glucoside in radix astragali seu hedysari by an ASE-HPLC (Accelerated Solvent Extraction-High Performance Liquid Chromatography) method. The method has the advantages of less time consumption for extraction and high detection precision and belongs to the field of chemical detection. The method comprises the following steps: extracting radix astragali seu hedysari powder by adopting an ASE method and collecting a methanol extracting solution; determining the content of the calycosin-7-glucoside in the methanol extracting solution by adopting an HPLC method. The method can be used for replacing a pharmacopoeia method to extract the calycosin-7-glucoside in the radix astragali seu hedysari and detect the content of the calycosin-7-glucoside.
