Comparison of aerial parts of Astragalus membranaceus and Astragali Radix based on chemical constituents and pharmacological effects

This study aims to provide a scientific basis for the comprehensive utilization of the aerial parts of Astragalus membranaceus (APAM). UPLC-Qtrap HRMS was used to identify secondary metabolites in APAM and Astragali Radix (AR), the pharmacological effects of them in N-acetyl phenylhydrazine (APH) and cyclophosphamide (Cy)-induced mice were studied by using 1H NMR-based metabolomics. The results showed that the secondary metabolites of APAM and...
