摘　　要：以商洛市所产杜仲叶为原料,乙醇为浸提溶剂,通过正交试验确定杜仲叶中绿原酸的最佳提取工艺。试验结果表明:杜仲叶中绿原酸的最佳提取条件为乙醇浓度60%,温度80℃,提取时间2.5 h,料液比1:20。最佳工艺条件下绿原酸的提取率为2.114%。试验提取方法简便,结果准确可靠,可为商洛市杜仲叶中绿原酸的生产开发提供参考。Alcohol-water mixture was used to extract chlorogenic acid from eucommia ulmoides leaves of Shangluo City. The optimum technological conditions were as follows： alcohol concentration was 60 percent, extraction temperature was 80℃, extration time was 2.5 h, and solid to liquid ratio was 1：20. Extration ratio of ehlorogenic acid was 2.114% under the optimum conditions.The extration method was simple and the result was accurate. It is valuable for chlorogenic acid extraction from eueommia ulmoides leaves in quantity.
