Quercetin Glycosides
Quercetin is a plant flavonol from the flavonoid group of polyphenols. It is found in many fruits, vegetables, leaves, seeds, and grains; capers, red onions, and kale are common foods containing appreciable amounts of it. It has a bitter flavor and is used as an ingredient in dietary supplements, beverages, and foods. Occurrence Quercetin is a flavonoid widely distributed in nature. The name has been used since 1857, and is derived from ''quercetum'' (oak forest), after the oak genus ''Quercus''. It is a naturally occurring polar auxin transport inhibitor. Quercetin is one of the most abundant dietary flavonoids, with an average daily consumption of 25–50 milligrams. In red onions, higher concentrations of quercetin occur in the outermost rings and in the part closest to the root, the latter being the part of the plant with the highest concentration. One study found that organically grown tomatoes had 79% more quercetin than non-organically grown fruit. Quercetin is pre ...

Flavonol
Flavonols are a class of flavonoids that have the 3-hydroxyflavone backbone (IUPAC name : 3-hydroxy-2-phenylchromen-4-one). Their diversity stems from the different positions of the phenolic -OH groups. They are distinct from flavanols (with "a") such as catechin, another class of flavonoids. Flavonols are present in a wide variety of fruits and vegetables. In Western populations, estimated daily intake is in the range of 20–50 mg per day for flavonols. Individual intake varies depending on the type of diet consumed. The phenomenon of dual fluorescence (due to excited state intramolecular proton transfer or ESIPT) is induced by tautomerism of flavonols (and glucosides) and could contribute to plant UV protection and flower colour. Besides being a subclass of flavonoids, flavonols are suggested by a study of cranberry juice to play a role along with proanthocyanidins, in the juice's ability to block bacterial adhesion, demonstrated by the compressing the fimbria of ' ...

Tomato
The tomato is the edible berry of the plant ''Solanum lycopersicum'', commonly known as the tomato plant. The species originated in western South America, Mexico, and Central America. The Mexican Nahuatl word gave rise to the Spanish word , from which the English word ''tomato'' derived. Its domestication and use as a cultivated food may have originated with the indigenous peoples of Mexico. The Aztecs used tomatoes in their cooking at the time of the Spanish conquest of the Aztec Empire, and after the Spanish encountered the tomato for the first time after their contact with the Aztecs, they brought the plant to Europe, in a widespread transfer of plants known as the Columbian exchange. From there, the tomato was introduced to other parts of the European-colonized world during the 16th century. Tomatoes are a significant source of umami flavor. They are consumed in diverse ways: raw or cooked, and in many dishes, sauces, salads, and drinks. While tomatoes are fruits†...

Cranberry
Cranberries are a group of evergreen dwarf shrubs or trailing vines in the subgenus ''Oxycoccus'' of the genus ''Vaccinium''. In Britain, cranberry may refer to the native species ''Vaccinium oxycoccos'', while in North America, cranberry may refer to ''Vaccinium macrocarpon''. ''Vaccinium oxycoccos'' is cultivated in central and northern Europe, while ''Vaccinium macrocarpon'' is cultivated throughout the northern United States, Canada and Chile. In some methods of classification, ''Oxycoccus'' is regarded as a genus in its own right. They can be found in acidic bogs throughout the cooler regions of the Northern Hemisphere. Cranberries are low, creeping shrubs or vines up to long and in height; they have slender, wiry stems that are not thickly woody and have small evergreen leaves. The flowers are dark pink, with very distinct ''reflexed'' petals, leaving the style and stamens fully exposed and pointing forward. They are pollinated by bees. The fruit is a berry that i ...

Buckwheat
Buckwheat (''Fagopyrum esculentum''), or common buckwheat, is a flowering plant in the knotweed family Polygonaceae cultivated for its grain-like seeds and as a cover crop. The name "buckwheat" is used for several other species, such as '' Fagopyrum tataricum'', a domesticated food plant raised in Asia. Despite its name, buckwheat is not closely related to wheat. It is not a cereal, nor is it even a member of the grass family. Buckwheat is related to sorrel, knotweed, and rhubarb, and is known as a pseudocereal because its seeds' culinary use is the same as cereals, owing to their high starch content. Etymology The name "buckwheat" or "beech wheat" comes from its triangular seeds, which resemble the much larger seeds of the beech nut from the beech tree, and the fact that it is used like wheat. The word may be a translation of Middle Dutch ''boecweite'': ''boec'' (Modern Dutch ''beuk''), "beech" (see PIE *''bhago''-) and ''weite'' (Mod. Dut. ''tarwe'', antiquated Dut. '' ...

Chokeberry
''Aronia'' is a genus of deciduous shrubs, the chokeberries, in the family Rosaceae native to eastern North America and most commonly found in wet woods and swamps. The genus Aronia is considered to have 3 species. The most common and widely used is ''Aronia melanocarpa'' (black chokeberry) which emerged from Eastern North America. The lesser known ''Aronia arbutifolia'' (red chokeberry) and the hybrid form of the abovementioned species called ''Aronia prunifolia'' (purple chokeberry) were first cultivated in Central and Eastern North America. In the eighteenth century, the first shrubs of the best-known species ''Aronia melanocarpa'' reached Europe where they were first cultivated in Scandinavia and Russia. Chokeberries are cultivated as ornamental plants and as food products. The sour berries, or aronia berries, can be eaten raw off the bush, but are more frequently processed. They can be used to make wine, jam, syrup, juice, soft spreads, tea, salsa, extracts, beer, ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watercress
Watercress or yellowcress (''Nasturtium officinale'') is a species of aquatic flowering plant in the cabbage family Brassicaceae. Watercress is a rapidly growing perennial plant native to Europe and Asia. It is one of the oldest known leaf vegetables consumed by humans. Watercress and many of its relatives, such as garden cress, mustard, radish, and wasabi, are noteworthy for their piquant flavors. The hollow stems of watercress float in water. The leaf structure is pinnately compound. Small, white, and green inflorescences are produced in clusters and are frequently visited by insects, especially hoverflies, such as ''Eristalis'' flies. Taxonomy Watercress is listed in some sources as belonging to the genus ''Rorippa'', although molecular evidence shows those aquatic species with hollow stems are more closely related to ''Cardamine'' than ''Rorippa''. Despite the Latin name, watercress is not particularly closely related to the flowers popularly known as nasturtiums (''Trop ...

Radicchio
Radicchio ( or ; ) is a perennial cultivated form of leaf chicory (''Cichorium intybus'', Asteraceae) sometimes known as Italian chicory because of its common use in Italian cuisine. It is grown as a leaf vegetable and usually has colorful white-veined red leaves that form a head. Radicchio has a bitter and spicy taste which mellows if it is grilled or roasted. History Pliny the Elder said that radicchio was useful as a blood purifier and an aid for insomniacs in ''Naturalis Historia''. Radicchio contains intybin, a sedative/analgesic, as well as a type of flavonoid, called anthocyanin. Modern cultivation of the plant began in the fifteenth century in the Veneto, Friuli Venezia Giulia and Trentino regions of Italy, but the deep-red radicchio of today was engineered in 1860 by Belgian agronomist Francesco Van den Borre, who used a technique called ''imbianchimento'' (whitening), ''preforcing'', or blanching to create the dark red, white-veined leaves. The plants are taken fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
