Methods The samples were prepared by SPE C18 column. HPLC-DAD-MS method was used to identify the flavonoids in Astragali Radix decoction. The chemical constituents of the library were compared with the measured mass charge ratio of chemical composition in Astragali Radix decoction, and the chemical constituents was determined by the pyrolysis law of the compounds. Results HPLC-MS provided high analysis efficiency of chemical components in Astragali Radix decoction. Based on the mass information and MS fragmentation behaviors of the chemical components, 22 compounds in Astragali Radix decoction were identified. Conclusion HPLC-MS technology can quickly characterize the flavonoids in in Astragali Radix decoction, and provide a new idea for the study of its pharmacodynamic material basis"/>
