D\u00e9finition scientifique des polyph\u00e9nols<\/figcaption><\/figure><\/div>\n\nSensu stricto, les polyph\u00e9nols se caract\u00e9risent par la pr\u00e9sence d’au moins deux groupements ph\u00e9noliques associ\u00e9s dans des structures plus ou moins complexes, g\u00e9n\u00e9ralement de haut poids mol\u00e9culaire.
