Metal complexing assays (i.e. Jerumanis method) are generally more specific than redox-based assays, because the color of the complexes depends on a specific pattern of substitution on the phenolic rings [108]. Procyanidins form chelates with metal ions via their ortho-diphenolic groups on the B-rings [112],...
