Quercetin Metabolites In Plasma of Rats Fed Diets Containing Rutin or Quercetin [PDF]

The Journal of Nutrition, 1995
We studied the bioavailability and the plasma transport of flavonols in rats fed quercetin or rutin diets. Wistar rats were fed one of the following purified diets for 10 d: control; 16.4 or 8.2 mmol rutin/kg diet; or 16.4, 8.2 or 4.1 mmol quercetin/kg diet. Flavonol concentrations were determined in plasma, ileal and cecal contents, and feces. In rats

Antioxidant Properties of Quercetin

2011
Quercetin, a plant-derived aglycone form of flavonoid glycosides, has been used as a nutritional supplement and may be beneficial against a variety of diseases, including cancer. We examined the antioxidant properties of quercetin. The reduction potential of quercetin was measured at various pH values using voltammetric methods, and its total ...

Pharmacokinetics of quercetin from quercetin aglycone and rutin in healthy volunteers

European Journal of Clinical Pharmacology, 2000
Quercetin is a flavonoid with a wide range of biological activities. It mainly occurs in plants as glycosides, such as rutin (quercetin rutinoside) in tea. Quercetin and rutin are used in many countries as vasoprotectants and are ingredients of numerous multivitamin preparations and herbal remedies.The primary objective was to characterise and compare ...

Molecular imaging of the biological effects of quercetin and quercetin-rich foods

Mechanisms of Ageing and Development, 2004
The human diet contains several thousands of organic plant molecules (i.e. phytochemicals), many of which have significant bioactivities. The specific physiological effects of these compounds are impossible to predict from in vitro studies using cell cultures and cell-free model systems. Nutrigenomics, which may be defined as the application of genomic

Adsorption Isotherms of Quercetin and Catechin Compounds on Quercetin-MIP

Chemical Research in Chinese Universities, 2007
A molecular imprinted polymer(MIP) was prepared with quercetin as the template and methacrylic acid(MAA) as the functional monomer. Acetonitrile and methanol were used as the porogen with ethylene glycol dimethacrylate (EGDMA) as the crosslinker and 2,2′-azobis(isobutyronitrile) (AIBN) as the initiator.

Metabolic activation of quercetin mutagenicity

Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1990
The mutagenicity of quercetin was reinvestigated using the Salmonella/microsome test. The mutagenicity of quercetin was enhanced by the cytosolic fraction of liver extract (S100), or by ascorbate, and even more by the complete liver supernatant (S9) in the presence of cofactors (NADP and glucose-6-phosphate).

The oxidation of natural flavonoid quercetin

Chemical Communications, 2012
This study explains the controversies in the literature concerning the number of electrons involved in the oxidation of quercetin. This stems from inappropriate handling samples, which require strict anaerobic conditions. The redox potential of quercetin strongly depends on the pH and on the presence of dissociation forms in solution.

In vitrodegradation of the flavonol quercetin and of quercetin glycosides in the porcine hindgut

Archives of Animal Nutrition, 2006
The present study investigated the microbial degradation of the plant flavonol quercetin and its naturally occurring glycosides isoquercitrin and rutin in the porcine hindgut. The experiments were carried out with the semicontinuous colon-simulation technique.
