【Abstract】 PurposeTo choose suitable macroporous adsorption resins to enrich the active compound from Eucommia ,and pinoresinol d gluside (PDG), which show anti hypertensive activity.MethodsAdsorption and desorption characteristics of PDG were carried out on the resins. HPLC was used to determine the content of PDG.ResultsThe better resin S 8 was chosen, and the optimum parameters were obtained. The content of PDG was increased from 0.085% in the raw material to 38.5% in the product with a recovery of 85.5%.ConclusionThe resin adsorption is practicable method to isolate and purify PDG from Eucommia.更多还原
