摘要: 目的:从诃子中分离制备具有拮抗 CPG ODN 作用的活性组分 。方法:应用水提 、离子色谱技术等 方法 ,从诃子中分离制备具有拮抗 CPG ODN 活性的 组分 ;并应用生物传感器技术 ,对所得到的组分进行 与CPG ODN 结合活性的筛选;观察其对 CPG ODN 刺激的小鼠 RAW 264 .7 细胞释放炎症介质的抑制 作用。结果 :应用生物传感器技术筛选出与 CPG ODN 结合活性最高的诃子作为研究对象, 应用离子 色谱技术从诃子中分离出 3 组分, 其中有 3 个组分 均具有一定的与 Lipid A 的结合活性, 以第 3 组分与 Lipid A 的结合活性最强;并对CPG ODN 刺激的小鼠 RAW 264 .7 细胞释放 TNF-α具有显著的抑制作用 ; 结论 :从诃子中分离出的第 3 组分具有显著的拮抗 CPG ODN 活性。

Abstract: AIM:To extract different components from Terminaliachebula retz and evaluate their anti-CPG ODN activities .METHODS :Anti- CPG ODN fractions were extracted through water extraction and ion-exchange HPLC.Their binding activities to CPG ODN were select- ed through sensor technology .Their inhibiting activity to the release of TNF-αfrom RAW 264 .7 was determined . RESULTS :Three anti-CPG ODN fractions were extract- ed from Terminaliachebula ret .Terminaliachebula retz 3 fraction was proved to have most powerful binding activity to CPG ODN , and inhibit the release of TNF-αof RAW 264 .7 .CONCLUSION:The Terminaliachebula retz 3 fraction has marked anti-CPG ODN activity .

Key words: Terminaliachebula retz ;anti-CPG ODN , active fraction ;sensor technology
