Abstract：The process of purification of crude tea polyphenols by column chromatography was investigated. The method was carried out with silica gel as adsorbent and ethyl acetate as elution. Thus, tea polyphenols was obtained which the content of catethin was over 90% and the total content of EGCG, GCG and ECG was over 75%, the content of caffeine was unchecked by HPLC. The results showed that this method was effective and simple.
