杜仲叶Eucommiae Folium作为一种药食同源中药，具有较高的药用价值。其药用品质特征主要由有效成分、重金属及微量元素3类指标共同决定，分别关联药用功效、安全风险及营养增益。通过收集并整理相关文献，系统分析了生长年限、采收时期、产地及种植模式对杜仲叶品质的影响规律，讨论杜仲叶药用品质的影响因素及其影响机制。并深入了解杜仲叶药用潜力，及对杜仲叶下一步在品质、采收时期、种植模式的研究内容进行展望，为杜仲叶的质量控制及资源合理开发利用提供参考依据。

Duzhongye (Eucommiae Folium), as a traditional Chinese medicine with medicinal and edible homology, possesses high medicinal value. Its medicinal quality characteristics are mainly determined by three categories of indicators: Effective components, heavy metals and trace elements, which are respectively related to medicinal efficacy, safety risk and nutritional gains. By collecting and sorting out relevant literature, the effects of groeth years, harvestperiods, producing areas and planting patterns on the quality of Eucommiae Folium were systematically analyzed, and the influencing factors and their mechanism of the medicinal quality of Eucommiae Folium were discussed. In addition, this paper deeply understands the medicinal potential of Eucommiae Folium, and prospects future research on its quality, harvest periods and planting patterns, to provide a reference for the quality control of Eucommiae Folium and the rational development and utilization of its resources.
