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

The objective of this study was to assess the influence of the peroxidase/coniferyl alcohol (CA) ratio on the dehydrogenation polymer (DHP) synthesis. The soluble and unsoluble fractions of horseradish peroxidase (HRP)-catalyzed CA dehydrogenation mixtures were recovered in various proportions, depending
