Common_NameQuercetin
DescriptionQuercetin is a flavonoid and more specifically a flavonol and represents 60% of the total dietary flavonols intake. The term flavonoid comprises several thousand plant derived compounds sharing a common skeleton of phenylchromane. This basic structure allows a multitude of substitution patterns leading to several flavonoid subclasses such as flavonols, flavones, flavanones, catechins, anthocyanidins, isoflavones, dihydroflavonols and chalcones. They are widely distributed in the plant kingdom, being present in variable amounts in dietary fruits, vegetables, nuts, seeds, herbs, spices, tea and red wine. Human daily intake of flavonols plus flavones has been estimated to be 22 to 23 mg. The interest in dietary flavonoids has grown after the publication of several epidemiological studies showing an inverse correlation between dietary consumption of flavonols and flavones and reduced incidence and mortality from cardiovascular disease and cancer. In recent years, a large amount of experimental and some clinical data have accumulated regarding the effects of flavonoids on the endothelium under physiological and pathological conditions. The meta-analysis of seven prospective cohort studies concluded that the individuals in the top third of dietary flavonol intake are associated with a reduced risk of mortality from coronary heart disease as compared with those in the bottom third, after adjustment for known risk factors and other dietary components. A limited number of intervention studies with flavonoids and flavonoid containing foods and extracts has been performed in several pathological conditions. (PMID: 17015250)
