PurposeTo choose suitable macroporous adsorption resins to enrich the active compound from Eucommia ,and pinoresinol d gluside (PDG), which show anti hypertensive activity.

目筛选效果较好树,对杜仲降压活性成二葡糖苷进行有效富集,提高产品质量。

A study was made of the effect of using silica gel and macroporous resin I as absorbent in column chromatography on the separation of tigogenin.

究用硅胶、大孔树Ⅰ作为吸附剂柱色离效果。

Tigogenin was separated completely from the crude sapogenins by macroporous resin column chromatography,only simple solvent Ilelute was used in the column of the separate process.

用大孔树为吸附剂色方法在离过程中仅需要简单溶剂-Ⅱ,离出单一组剑麻皂甙元占粗皂甙元比率高达70%以上。
