The present invention provides a method of producing a theaflavin composition rich in mono-gallated theaflavin. The method comprises the steps of: a) providing a mixture of theaflavins; b) contacting the mixture of theaflavins with phospholipid and a solvent thereby to form a complex comprising the phospholipid and the theaflavin composition; and c) separating the complex from the remaining theaflavins.
