目的 以吴茱萸的归经研究为例，构建基于系统生物学从次生代谢物作用蛋白受体角度研究中药归经的新方法。方法 建立吴茱萸的次生代谢物成分-作用受体的复杂网络，以至少与5个化合物高度选择为条件选取蛋白受体，并将受体组织器官分布、功能与吴茱萸归经脏腑循经器官与功效互相比较应证。结果 共获得吴茱萸的次生代谢物高度选择作用的34个受体，其分布和功能与吴茱萸传统归经的循经解剖器官组织归位及功效高度一致。结论 应用本方法从成分作用受体角度说明中药归经的现代科学物质基础及机制，将助推归经相关研究，具有重要的参考价值。

Objective Using meridian tropism of Evodiae Fructus as an example, a new method was built based on system biological method to study the tropism of Chinese herbal medicine from the view of secondary metabolites acting with protein receptors. Methods After establishing the complex secondary metabolites compounds-receptors network of Evodiae Fructus, the receptors connecting with at least five compounds were selected. These functions and tissue distribution of receptors were compared with the traditional efficacy and meridian viscera and organs of Evodiae Fructus. Results A total of 34 receptors of secondary metabolites of Evodiae Fructus were acquired. Their functions and distributions were consistent highly with the traditional efficacy and meridian tropism of Evodiae Fructus locating anatomical organs and tissues. Conclusion This original innovation method clearly elucidated the modern scientific material basis and mechanism of the meridian tropism of Chinese herbal medicine from the aspect of component action receptor. Also it will be of important reference value for the study of promoting meridian tropism.
