树脂法纯化茶多酚的研究

Purification of Tea Polyphenol with Macroporous Adsorption Resin

比较了不同树脂对茶多酚的吸附特性 ,筛选出适合于茶多酚分离纯化的吸附树脂。结果显示 ,当初始样品的茶多酚纯度为 6 8 5 % ,供试液的茶多酚含量为 10mg/mL ,以 80 %乙醇作为洗脱剂 ,洗脱速度为 0 8mL/min ,茶多酚纯度可达 95 8%。

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%.
