  • Augmente l'activité antitoxique du foie
  • Anti-inflammatoire [19], [20], [21]
  • Anti-allergique [22], [23]
  • Antiviral (réduction dose-dépendante de l'infectivité, diminue la réplication intracellulaire) [24]
  • Antibactérien et antifongique surtout par certains dérivés (quercétine-3,7-O-α-l-dirhamnoside) [25]
  • Propriétés pseudo-oestrogéniques, inhibition de la perte osseuse et stimulation de la formation osseuse, par inhibition de l'activité des ostéoclastes et stimulation de l'activité des ostéoblastes [26]
  • Effet anti-abortif par activité immunologique [27]
  • La quercétine intervient dans la photo protection chez les végétaux [28]
