*4.2.8 Flavonoids*

Flavonoids are low in molecular weight and are the main type of phenolic compounds in plants. They are structured by 15 carbon atoms, organized in a C6-C3-C6 configuration. Due to their high redox potential, flavonoids are, in particular, important antioxidants that allow them to function as reducing agents, hydrogen donors, and singlet oxygen quenchers. In addition, they include a metal chelating potential [55].
