Multi-index integrated evaluation of spectrum-effect relationship on immunocompetence of Radix Astragali
(2.Gansu Entry-Exit Inspection and Quarantine Bureau Central Laboratory of Technical Center, Lanzhou , China 730000)
【Abstract】The study was aimed to investigate the correlation between the immunocompetence and the fingerprints of supernatant extracts from Radix Astragali by multi-index integrated evaluation, and reveal the material basis of Radix Astragali improving the immunological function. After oral administration 10 batch of supernatant extracts from Radix Astragali on immunosuppressed mice, phagocytic index, delayed type hypersensitivity (DTH) degree, organs index and the level of cytokines IFN-γ, IL-4 (ELISAs) were measured, and each common peak from HPLC-DAD/HPLC-ELSD fingerprints were correlated with the above data. A number of components in supernatant extracts of Radix Astragali display a substantial correlation with the immunocompetence.Supernatant extracts of Radix Astragali can significantly enhance immunological function on mice, which is related to various components in Radix Astragali.
