Abstract:

Macroporous resin adsorption was used to obtain high-purity oleuropein from Syringa pubescens Turcz., an effective antihepatic fibrosis component. Six common macroporous absorption resins were compared for differences in adsorption and desorption performance. D-101 resin was found to be the best choice for oleuropein purification. To achieve an optimal oleuropein purification, the adsorption and desorption characteristics of D-101 resin were investigated. Results showed that the purity of purified crude Syringa pubescens Turcz. oleuropein using D-101 resin under optimized adsorption-desorption conditions was more than 30%. Forty percent aqueous ethanol solution was a fast and effective solvent for oleuropein desorption. D-101 resin exhibited good reusability. This method is easy and convenient in operation and has promising potential for industrial application.
