Abstract: | Ethnopharmacological relevanceThe immunomodulatory capacities of fresh Cordyceps militaris (FCM) and dry Cordyceps militaris (DCM) were compared.Materials and methodsIn vivo immunomodulatory assay, different doses of FCM and DCM were orally administrated over a period of 15 days in a cyclophosphamide (CY) induced immunosuppression mice; in vitro testing, the spleen cells were extracted from healthy mice and treaded with CY, then cultured with different dose of FCM or DCM; the contents of Cordyceps militaris polysaccharide (CMP), cordycepin, adenosine, total polyphenol (TP) and total flavonoids (TF) in FCM and DCM were measured.ResultsOur studys indicated that, FCM was significantly stronger than DCM on increasing the spleen and thymus indexes, spleen lymphocyte activity, macrophage function, and promoting the levels of IL-2, IFN-γ in vivo and in vitro. The contents of immunomodulatory CMP and TF in FCM were markedly higher than in DCM.ConclusionAll these results suggested that FCM was superior to DCM on enhancing immunity. |
