Separation and purification of EGCG in grean tea polyphenols by cellulose acetate—EGCG molecularly imprinted composite membrane

ZHANG Chunjing,ZHONG Shi′an(School of Chemistry and Chemical Engineering,Central South University,Changsha 410083,China)  
An EGCG molecularly imprinted composite membrane was prepared using porous cellulose acetate membrane as support,and the membrane was employed to separate and purify EGCG in grean tea polyphenols.The detecting results of EGCG obtained by HPLC indicated that the high purification EGCG(mass fraction 93%) could be obtained by the method.
【Key Words】： cellulose acetate membrane grean tea polyphenols EGCG molecularly imprinted composite membrane separation
