Flavonoids are polyphenolic plant secondary metabolites with antioxidant and other
biological activities potentially beneficial to health. Food-borne flavonoids occur mainly as
glycosides, some of which can be absorbed in the human small intestine; however, the
mechanism of uptake is uncertain. We used isolated preparations of rat small intestine to
compare the uptake of the quercetin aglycone with that of some quercetin glucosides
commonly found in foods, and investigated interactions between quercetin-3-glucoside and …
