This method utilizes the ability of the tannins to precipitate with protein. Separation conditions were investigated using model solutions. This method is uncomplicated, inexpensive and suitable for real samples. About 34% of the total Al in brew extracted from commercially available teas was bound to condensed and hydrolyzable tannins.eninfo:eu-repo/semantics/closedAccessSpeciationPolyphenolsQuantitationCatechinsExtractsArticle218100510081612217710.2116/analsci.21.1005WOS:000231180200022Q3
