Abstract
The adsorption properties of different macroporous resins for tea polyphenol were studied One of them was the most suitable for purifying tea polyphenol The results showed that when the initial sample with the tea polyphenol purity 68.5% was prepared to be 10 mg/mL solution,then adsorbed by the optimal resin,and eluted with 80% ethanol and the eluted rate of 0.8 mL/min the tea polyphenol purity could reach 95.8%.
