摘要
采用正交设计实验研究了有机溶剂体积分数、提取次数、提取时间和料液比对杜仲叶水溶性活性成分提取的影响,确定了最佳提取工艺,实验中发现,有机溶剂体积分数影响最大,提取时间和提取次数影响次之,料液比影响不大.
In order to optimize the technology of extracting process of watersoluble active components of Folium Eucommiae, L9(34) orthogonal layout were used to select the best conditions by different processing methods of Folium Eucommiae with different specifications: volume shares of solvent (A), times of extracting(B), time of extracting(C) and ratio of materials to solvent (D). Results: The best condition was A1B2C1D2. The factor A effected its quality the most, B and C secondly, D least and insignificantly.
