Abstract: In this study,MTT and ELISA methods were used to investigate the effects of flavonoid and flavone from Eucommia ulmoides Oliv.on prolifeation of splenocytes and production of IL-2 and IFN-γ in mice.The results showed that flavonoid extract of E.ulmoides Oliv.and quercetin can siganificantly upregulate prolifeation and production of IL-2 and IFN-γ in lymphocytes stimulated by ConA or LPS.Along with the extension of time,compared with the blank group,the experimental results changed significantly.The results of multiple significance analysis showed that there was certain dose concentration dependence.However,kaempferol can effectively inhibit proliferation and production of cytokine in a certain concentration range.

Key words: flavonoid of Eucommia ulmoides Oliv., quercetin, kaempferol, immunity, lymphocytes
