Abstract: Flavonoids and biochemically-related chalcones are important secondary
metabolites, which are ubiquitously present in plants and therefore also in human food.
They fulfill a broad range of physiological functions in planta and there are numerous
reports about their physiological relevance for humans. Flavonoids have in common a basic
C -C -C skeleton structure consisting of two aromatic rings (A and B) and a heterocyclic
6 3 6
ring (C) containing one oxygen atom, whereas chalcones, as the intermediates in the
formation of flavonoids, have not yet established the heterocyclic C-ring. Flavonoids are
grouped into eight different classes, according to the oxidative status
