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 mg. 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 present in va ...

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, and an unrelated group of metabolically important molecules, the flavins (with "i"), derived from the yellow B vitamin riboflavin. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coriander
Coriander (), whose leaves are known as cilantro () in the U.S. and parts of Canada, and dhania in parts of South Asia and Africa, is an annual plant, annual herb (''Coriandrum sativum'') in the family Apiaceae. Most people perceive the leaves as having a fresh, slightly citrus taste. Due to variations in the gene OR6A2, some people perceive it to have a soap-like taste, or even a pungent or rotten taste. It is native to the Mediterranean Basin. All parts of the plant are edible, but the fresh leaves and the dried seeds are the parts most traditionally used in cooking. It is used in certain cuisines, like Mexican cuisine, Mexican, Indian cuisine, Indian and Southeast Asian cuisine, Southeast Asian. Description It is a soft plant growing to tall. The leaves are variable in shape, broadly lobed at the base of the plant, and slender and feathery higher on the flowering stems. The flowers are borne in small umbels, white or very pale pink, asymmetrical, with the petals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tomato
The tomato (, ), ''Solanum lycopersicum'', is a plant whose fruit is an edible Berry (botany), berry that is eaten as a vegetable. The tomato is a member of the nightshade family that includes tobacco, potato, and chili peppers. It originated from and was domesticated in western South America. It was introduced to the Old World by the Spanish in the Columbian exchange in the 16th century. Tomato plants are vines, largely Annual plant, annual and vulnerable to frost, though sometimes living longer in greenhouses. The flowers are able to self-fertilise. Modern varieties have been bred to ripen uniformly red, in a process that has impaired the fruit's sweetness and flavor. There are thousands of cultivars, varying in size, color, shape, and flavor. Tomatoes are attacked by many insect pests and nematodes, and are subject to diseases caused by viruses and by mildew and blight fungi. The tomato has a strong savoury umami flavor, and is an important ingredient in cuisines around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. Buckwheat originated around the 6th millennium BCE in the region of what is now Yunnan, Yunnan Province in southwestern China. 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. Buckwheat is not a cereal, nor is it a member of the Poaceae, grass family. It is related to sorrel, Polygonum, knotweed, and rhubarb. Buckwheat is considered a pseudocereal because the high starch content of the seeds enables buckwheat to be cooked and consumed like a cereal. Etymology The name "buckwheat" or "beech wheat" comes from its tetrahedral seeds, which resemble the much larger seeds of the beech nut from the beech, beech tree, and the fact that it is used like wheat. The word may be a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vaccinium Uliginosum

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 above mentioned 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 an ornamental plant and as a food plant. The sour berries, or aronia berries, can be eaten fresh off the bush, but are more frequently processed. They can be used to make wine, jam, syrup, juice, soft spreads, tea, salsa, extracts, beer, ... [...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 Eurasia. 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. Description Watercress can grow up to in length. The stems are hollow and 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''.

Radicchio
Radicchio is a perennial cultivated form of leaf chicory (''Cichorium intybus'', Asteraceae), commonly used in Italian cuisine. It is grown as a leaf vegetable and usually has colourful, white-veined red leaves that form a head. Radicchio has a bitter and spicy taste that mellows if it is grilled or roasted. History Pliny the Elder wrote in ''Naturalis Historia'' that radicchio was useful as a blood purifier and an aid for insomniacs. 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 from the soil and placed in water in darkened ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
