摘要: 采用MTT法和ELISA技术,通过考察不同纯度的杜仲黄酮对小鼠脾淋巴细胞增殖及细胞因子IL-2和IFN-γ诱生作用的影响,初步探讨杜仲黄酮的免疫活性。结果表明,杜仲黄酮粗品及槲皮素均对经ConA或LPS刺激下的小鼠脾淋巴细胞的增殖和细胞因子IL-2与IFN-γ的分泌有协同作用;随细胞培养时间延长,与空白组比较作用效果也逐渐显著。多重显著性分析结果显示,在一定范围内,不同浓度的样品对脾淋巴细胞的增殖效果存在差异,并有一定的浓度依赖性。而山奈酚则随浓度的升高对淋巴细胞的增殖呈抑制趋势,同时对细胞因子的诱生起下调作用。

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
