Using a DSS-induced colitis mice model, treatment with quercetin aglycone alone or quercetin aglycone with monoglycosides counteracted both inflammatory response and oxidative stress, by lowering the malondialdehyde (MDA), reduced glutathione (GSH), serum nitrate (NO), and myeloperoxidase (MPO) concentrations [134]. Here, MPO is linked to colitis.
