从杜仲叶中提取绿原酸纯品的研究

A Study on the Isolation of Chlorogenic Acid from the Leaves of Eucommia ulmoides

用化学萃取、无机盐沉淀等方法首次从杜仲叶中提取、分离出绿原酸纯品，其纸色谱和紫外光谱特征与文献相符；

Chlorogenic acid was first isolated from the leaves of Eucommia ulmoides by chemical extraction and precipitation. Its paper chromatography and ultraviolet spectrum were the same with literature. Its phamaceutical value and prospects of development were discussed.
