Quercetin is a dietary antioxidant that prevents oxidation of low-density lipoproteins in vitro. Intake of quercetin was inversely associated with coronary heart disease mortality in elderly Dutch men. However, the extent of absorption of quercetin in humans is unclear. The aim of this study was to quantify absorption of various forms of quercetin. Nine healthy ileostomy subjects were studied, to avoid losses caused by colonic bacteria. They followed a quercetin-free diet for 12 d; on days 4, 8… 

Figures and Tables from this paper

Quercetin glucosides are completely hydrolyzed in ileostomy patients before absorption.

Findings suggest that both QMG and QDG are efficiently hydrolyzed in the small intestine by beta-glucosidases to quercetin, most of which is then absorbed, a different interpretation than that from the previous study.

Determinants of the absorption of the dietary flavonoid quercetin in man

Oxidation of low density lipoprotein is hypothesised to play an important role in the development of cardiovascular disease. It might be prevented by dietary antioxidants. Quercetin is a dietary

Absorption of Quercetin and Rutin in Rat Small Intestine

Both quercetin and rutin can attach to and traverse theSmall intestine of the rat and binding of flavonoids to the intestinal wall components may however greatly limit their absorption from the small intestine.

The bioavailability of quercetin in pigs depends on the glycoside moiety and on dietary factors.

The results indicate that the bioavailability of quercetin from quERCetin glycosides is determined by a complex interdependence between the chemical form of the flavonols and dietary factors.

Accumulation of quercetin conjugates in blood plasma after the short-term ingestion of onion by women.

It is concluded that conjugated metabolites of quercetin accumulate exclusively in human blood plasma in the concentration range of 10(-7) approximately 10(-6) M after the short-term ingestion of vegetables rich in quERCetin glucosides, although these metabolites are hardly incorporated into plasma LDL.

Carbon dioxide is the major metabolite of quercetin in humans.

The disposition of quercetin in humans is thus highly complex, requiring further studies, as well as search for the unaccounted for fraction of the (14)CO(2) recovery studies in three volunteers.

Pharmacokinetics and Bioavailability of Quercetin Glycosides in Humans

The disposition of quercetin in humans primarily depends on the sugar moiety, and to a minor extent, the plant matrix influences both the rate and extent of absorption in the case of buckwheat tea administration compared with the isolated compound.

Comparison of the urinary excretion of quercetin glycosides from red onion and aglycone from dietary supplements in healthy subjects: a randomized, single-blinded, cross-over study.

Data from a two-period, two-sequence crossover study to compare the bioavailability of quercetin when administered in the form of a fresh red onion meal or dietary supplement under fasting conditions allow intervention studies on quercETin giving either food or supplements to be more effectively compared.



Metabolic fate of [14C] quercetin in the ACI rat.

The present data indicate that the lack of carcinogenicity of quercetin in the rat is attributable to neither its poor absorption from the digestive tract nor its microbial degradation in the tract.

Digestion of the polysaccharides of some cereal foods in the human small intestine.

This study supports the view that human digestive enzymes do not break down dietary NSP and identifies a fraction of starch, RS, present in processed food which resists breakdown by alpha-amylase both in vitro and in the small intestine of man.

Flavonoid intake and long-term risk of coronary heart disease and cancer in the seven countries study.

Average flavonoid intake may partly contribute to differences in coronary heart disease mortality across populations, but it does not seem to be an important determinant of cancer mortality.

Mammalian Metabolism of Flavonoids

Although earlier investigations of the mammalian metabolism of flavonoid compounds were largely concerned with the identification of their urinary metabolites (cf. De Eds, 1968), more recent studies

Pharmacokinetics and metabolism of oral diosmin in healthy volunteers.

The data show the total absence of urinary elimination for both diosmin and its aglycone diosmetin, while its minor metabolites are eliminated in the urine, mainly as glucuronic acid conjugates.

The use of 4-aminobenzoic acid as a marker to validate the completeness of 24 h urine collections in man.

PAB is a safe marker of the completeness of 24 h urine collections and any collection containing less than 205 out of 240 mg (85%) of PAB, given as 80 mg with each of three meals, is probably incomplete.

Effect of acute cigarette smoking on gastric secretion.

It is concluded that smoking reduces gastric secretion and the possibility that relative antral hypoacidity induced by regular smoking produces an increase in parietal cell mass via a feedback mechanism mediated by gastrin is discussed.
