In vitro catabolism of quercetin by human fecal bacteria and the antioxidant capacity of its catabolites

Food & Nutrition Research, 2014
Background: Part of quercetin flows into the colon after escaping the absorption of the small intestine and will be degraded by colonic microbiota. The catabolites in the colon partially determine the physiological activity of quercetin.

Stability of quercetin in DMEM and cell culture with A549 cells

eFood, 2022
Quercetin is evidently unstable in Dulbecco's modified Eagle's medium (DMEM) at 37°C. However, the underlying mechanism of this instability is not clear yet. The stability and new degradation products of quercetin in DMEM at 37°C were investigated via in

Quercetin attenuates renal ischemia/reperfusion injury via an activation of AMP-activated protein kinase-regulated autophagy pathway

, 2017
Renal ischemia/reperfusion (I/R) is a major cause of acute renal failure. Quercetin, a flavonoid antioxidant, presents in many kinds of food. The molecular mechanism of quercetin on renal protection during I/R is still unclear.
