Flavonoids Flavonoids are a large family of polyphenolic plant compounds. Six major subclasses of flavonoids, namely anthocyanidins, flavan-3-ols, flavonols, flavanones, flavones, and isoflavones, flavonols are the most widespread in the human diet. (More information)

- Flavonoids are 3-ring phenolic compounds consisting of a double ring attached by a single bond to a third ring. In leaves they block far ultraviolet (UV) light (which is highly destructive to nucleic acids and proteins), while selectively admitting light of blue and red wavelengths which is crucial for photosynthesis.etacyanins also produce the reddish color of flowers such as Bougainvillea.] Water soluble flavonoids (mostly anthocyanins) are responsible for the colors of many flowers and can range from red to blue, depending on the pH of the watery sap in the vacuoles.

Flavonoids Most flavonoids occur in edible plants and foods as β-glycosides, i.e., bound to one or more sugar molecules . Exceptions include flavan-3-ols (catechins and proanthocyanidins) and fermented soy-based products that are exposed to microbial β-glucosidases, which catalyze the release of sugar molecules from glycosylated isoflavones .

Foods Containing Phytochemicals Flavonoids are found in lots of grains, vegetables, and fruits. The flavonoids in soybeans, chickpeas, and licorice may act a little bit like estrogen, a hormone that might affect the risk of breast cancer that depends on estrogen for its growth. The estrogen-like compounds in these plants are called phytoestrogens.

- Researchers can now identify over 45 different flavonoids in kale. With kaempferol and quercetin heading the list, kale's flavonoids combine both antioxidant and anti-inflammatory benefits in way that gives kale a leading dietary role with respect to avoidance of chronic inflammation and oxidative stress.

- The flavonoids are a group of plant pigments, which exert antioxidant activity that is more potent and effective against a broader range of oxidants than the traditional antioxidant nutrients vitamins C and E, beta-carotene, selenium, and zinc.lavonoids are plant-based compounds with powerful antioxidant properties, which means they reduce inflammation, promote healthy arteries, and help fight aging by preventing -- and repairing -- cellular damage. Flavonoids may also protect against dementia, Alzheimer's disease, and some cancers.

What Does Fruit Give Us? All plant foods, including fruit, contain compounds called phytochemicals or phytonutrients, which provide powerful health benefits. Two main types of phytochemicals found in fruit are flavonoids and carotenoids. The University of Michigan Health System reports flavonoids, found in fruits such as cherries and red grapes, contain anthocyanins that help fight against heart disease and offer anti-inflammatory and anticancer protection.

- Abstract. Flavonoids are natural antioxidants derived from plants and commonly found in foods, such as fruits and vegetables, with the ability to sequester free radicals. Quercetin, part of a subclass of flavonoids called flavonols, has received considerable attention because of its overwhelming presence in foods.008). Three structural groups aid in quercetin's ability to maintain its stability and act as an antioxidant when reacting with free radicals: the B ring o-dihydroxyl groups, the 4-oxo group in conjugation with the 2,3-alkene, and the 3- and 5-hydroxyl groups (Hollman and Katan 1997).

- Hesperidin is an abundant flavonoid found in citrus fruits. It is the predominant flavonoid in lemons and oranges. The peel and membranous parts of these fruits have the highest hesperidin concentrations. Therefore, orange juice containing pulp is richer in the flavonoids and hesperidin than that without pulp. Sweet oranges (Citrus sinensis) and tangelos are the richest dietary sources of hesperidin. Hesperidin is classified as a Citrus bioflavonoid. Hesperidin, in combination with a flavone glycoside called diosmin, is used in Europe for the treatment of venous insufficiency and hemorrhoids.
