Content of potentially anticarcinogenic flavonoids of 28 vegetables and 9 fruits commonly consumed in the Netherlands
The content of the potentially anticarcinogenic flavonoids quercetin, kaempferol, myricetin, apigenin, and luteolin of 28 vegetables and 9 fruits was determined by RP-HPLC with UVdetection. FreshExpand
Intake of potentially anticarcinogenic flavonoids and their determinants in adults in The Netherlands.
The use of new analytic technology suggests that in the past flavonoid intake has been overestimated fivefold, but on a milligram-per-day basis, the intake of the antioxidant flavonoids still exceeded that of the antioxidants beta-carotene and vitamin E. Expand
Distribution, elimination, and toxicity of silver nanoparticles and silver ions in rats after 28-day oral exposure.
Oral exposure toSilver nanoparticles appears to be very similar to exposure to silver salts, however, the consequences of in vivo formation of silver nanoparticles, and of the long retention of silver in brain and testis should be considered in a risk assessment ofsilver nanoparticles. Expand
Polyphenols and disease risk in epidemiologic studies.
Plant polyphenols, a large group of natural antioxidants, are serious candidates in explanations of the protective effects of vegetables and fruits against cancer and cardiovascular diseases.Expand
Lignan contents of Dutch plant foods: a database including lariciresinol, pinoresinol, secoisolariciresinol and matairesinol
The aim of this study was to compile a lignan database including all four major enterolignan precursors, including lariciresinol and pinoresinol, in eighty-three solid foods and twenty-six beverages commonly consumed in The Netherlands. Expand
Chlorogenic acid and caffeic acid are absorbed in humans.
One third of chlorogenic acid and almost all of the caffeic acid were absorbed in the small intestine of humans, which implies that part ofchlorogenic acid from foods will enter into the blood circulation, but most will reach the colon. Expand
Relative bioavailability of the antioxidant flavonoid quercetin from various foods in man
It is concluded that conjugation with glucose enhances absorption from the small gut and repeated consumption of quercetin‐containing foods will cause accumulation of quERCetin in blood. Expand
Optimization of a quantitative HPLC determination of potentially anticarcinogenic flavonoids in vegetables and fruits
A rapid method based on RP-HPLC with UV detection is presented for the quantitative determination of five major flavonoid aglycons, viz. quercetin, kaempferol, myricetin, luteolin, and apigenin, inExpand
Flavonols, flavones and flavanols: nature, occurrence and dietary burden
Total flavonol and flavone contents of foods have been determined with validated state-of-the-art methods. Quercetin dominates, and flavonol levels found in vegetables and fruits are below 10 mgExpand
Absorption of dietary quercetin glycosides and quercetin in healthy ileostomy volunteers.
It is concluded that humans absorb appreciable amounts of quercetin and that absorption is enhanced by conjugation with glucose. Expand
