Polyphenols are antioxidants, which are known to influence bioavailability of metals in the body. The theaflavins of black tea are important members of this family, which have been sparsely investigated. The complexation of aluminium with purpurogallin (2,3,4,6-tetrahydroxy-5H-benzocyclohepten-5-one) has been investigated
