Abstract:

Theaflavins are a class of tea natural product with broad development prospects. Separation and preparation method of theaflavin monomers were reviewed, including cellulose chromatography, dextran gel chromatography, silica gel chromatography, polyamide adsorption resin chromatography and high speed counter current chromatograph, with their advantages and disadvantages compared. Polyamide adsorption resin chromatography was more satisfactory for separation and preparation of theaflavin monomer than others.

Key words: theaflavin, monomer, separation, preparation, polyamide
