目的 建立黄芪水煎液中黄酮类成分HPLC-MS鉴定方法。方法 黄芪水煎液采用C₁₈固相萃取小柱获得黄酮类化学成分。采用HPLC-DAD-MS的方法对黄芪水煎液中黄酮类成分进行了定性研究，对比所建立化合物库的化学成分与实测的化学成分质荷比信息以及化合物的裂解规律确定各化学成分。结果 液相色谱质谱联用技术可对黄芪水煎液所含黄酮类成分进行快速鉴别。根据相对分子质量信息确定了黄芪水煎液所含22个黄酮类化学成分的结构信息。结论 高效液相-质谱联用技术可快速对黄芪水煎液所含黄酮类成分进行表征，为其药效物质基础研究提供新思路。

Objective To establish an identification method for flavonoid chemical constituents in Astragali Radix decoction by HPLC-MS. 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
