Abstract:

To deproteinize from crude Epimedium polysaccharide, ADS-7 type of resin was selected from four kinds of macroporous adsorption resins.  The influence factors, such as pH value, tannic Acid, elution volume and so on, were investigated.  The content of proteins in crude Epimedium polysaccharide decreased from 1.2% to 0.035%.  The results show that deproteinization from crude Epimedium polysaccharide by macroporous adsorption resin is a feasible method.

Key words: Macroporous adsorption resin; Epimedium polysaccharide; Deproteinization
