Biological Activity

Quercetin is a common antioxidant flavonoid found in vegetables, which is usually present in glycosylated forms, such as quercitrin (3-rhamnosylquercetin), has anti-inflammatory effect which is mediated through the inhibition of the NF-kappaB pathway, inhibits cytokine and inducible nitric oxide synthase expression through inhibition of the NF-kappaB pathway without modification of c-Jun N-terminal kinase activity (both in vitro and in vivo). [1]
Quercetin has prevention of H2O2-induced apoptosis via anti-oxidant activity and heme oxygenase 1 gene expression in macrophages. [2]
Quercitrin exhibits a scavenger and antioxidant role, and these effects probably are mediated via different mechanisms, which may involve the negative modulation of the Fenton reaction and NMDA receptor. [3]
Quercetin( 50 μM)can reduce UVB-induced cell death and apoptosis in HaCaT cells, also similarly reduce UVB-induced ROS generation and cell death in live zebrafish. [4]
Quercitrin exhibits strong antioxidant and anti-carcinogenic activities, it contributes to the inhibition of neoplastic transformation by blocking activation of the MAPK pathway and stimulation of cellular protection signaling. [5]
Quercitrin and Taxifolin can stimulate osteoblast differentiation in MC3T3-E1 cells and inhibit osteoclastogenesis in RAW 264.7 cells, shows a positive effect of these flavonoids on bone metabolism. [6]
