杜仲叶中有效成分提取工艺的研究

A Study on the Extractive Technology of Effective Composition from the Leaf of Eucommia Ulmoides

采用了水提法、醇提法和超声波法３种提取工艺路线，以分光光度法为检测手段，以氯原酸为检测对象，得出了杜仲叶中有效成分提取过程的优化条件。

Three technological process:water extraction,alcohol extraction and ultrasonic wave extraction were used. By using the paper chromatography's UV spectrophotometer a better technological condition to extracting effective composition from the leaf of eucommia ulmoides is obtained.
