Abstract: By studying the characteristics of adsorbing apple polyphenol with AB-8 resin,the optimum conditions for separating and purifying apple polyphenol were obtained.The results showed that,when the purity of apple polyphenol of initial sample is 0.759%,the content of apple polypbenol of test solution is 1.648mg/ml,with 60% ethanol as eluting solvent, while the moving speed of is 1ml/min and the eluting speed 0.5ml/min.The purity of apple polyphenol can be up to 39.98%.

Key words: apple polyphenols, resin, adsorption, purification
