| Description | Isotrifoliin (Isoquercitroside)n is an effective antioxidant and an eosinophilic inflammation suppressor. |
| In vitro | Isoquercitrin occurs widely in plants.10 μM of Isoquercitrin of the seven compounds partially but significantly blunt the negative effect of H2O2 on RGC-5 cells, as the viability of cells in the presence of H2O2 is increased from approximately 63% to 83% and 90% at 10 and 50 μM, respectively. Indeed, 50 μM Isoquercitrin is more effective as a neuroprotectant than the same concentration of EGCG. |
| In vivo | In animals receiving Isoquercitrin or quercetin, eosinophil counts are lower in the BALF, blood and lung parenchyma. Neutrophil counts in blood and IL-5 levels in lung homogenate are lower only in Isoquercitrin-treated mice. No alterations in mononuclear cell numbers were observed. |
