摘要 通过测定七个产区杜仲叶中5种有效成分(次生代谢物)的含量，得出生态因素是调控药用植物有效成分合成与积累的重要因素。并对各种生态因素进行了逐步回归和通径分析，结果表明：影响杜仲叶有效成分合成与积累的主要因素是土壤中的微量元素，而气象因素影响不大。关键词 杜仲叶;有效成分;生态因素；微量元素

Abstract Through determining the contents of five active constituents (secondary metabolites) in Eucommia ulmoides leaves from seven regions,the author concluded that the ecological factors were important in regulating the synthesis and accumulation of active constituents of medicinal plant. Stepwise regression analysis and path analysis indicated that the major factor influencing the synthesis and accumulation of active constituents was the contents of trace elements in the soil. Meteorological factors,however,showed little influence.
Key words Eucommia ulmoides leaves ; active constituents; ecological factor
