Tangeritin
Tangeretin is an O- polymethoxylated flavone that is found in tangerine and other citrus ''Citrus'' is a genus of flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as oranges, lemons, grapefruits, pomelos, and limes. The genus ''Citrus'' is native to ... peels. Tangeretin strengthens the cell wall and acts as a plant's defensive mechanism against disease-causing pathogens.Uckoo, RM; et al. Sep. Purif. Technol. 2011. It has also been used as a marker compound to detect contamination in citrus juices. The following is a list of methods used to extract tangeretin from citrus peels: * column chromatography * preparative-high performance liquid chromatography * super critical fluid chromatography * high speed counter current chromatography * a combination of vacuum flash silica gel chromatography and flash C8 column chromatography * flash chromatography * isolation using ionic liquids and a cycle ...

O-methylated Flavone
The O-methylated flavonoids or methoxyflavonoids are flavonoids with methylations on hydroxyl groups (methoxy bonds). O-methylation has an effect on the solubility of flavonoids. Enzymes O-methylated flavonoids formation implies the presence of specific O-methyltransferase An O-methyltransferase (OMT) is a type of methyltransferase enzyme transferring a methyl group on a molecule. Examples are : * Acetylserotonin O-methyltransferase * Apigenin 4'-O-methyltransferase * Caffeate O-methyltransferase * Caffeoyl-CoA ... (OMT) enzymes which accept a variety of substrates. Those enzymes mediate the O-methylation on a specific hydroxyl group, like on 4' (example in ''Catharanthus roseus'') or 3' (example in rice) positions. Those positions can be Arene substitution patterns, ortho, meta, para and there can be a special 3-O-methyltransferase for the 3-OH position. Calamondin orange (''Citrus mitis'') exhibits all of those activities. Plant enzymes * Apigenin 4'-O-methyltransferase * 8 ...

Tangerine
The tangerine is a type of citrus fruit that is orange in color. Its scientific name varies. It has been treated as a separate species under the name ''Citrus tangerina'' or ''Citrus'' × ''tangerina'', or treated as a variety of ''Citrus reticulata'', the mandarin orange. ''Citrus tangerina'' is also treated as a synonym of ''Citrus deliciosa''. It is a group of orange-colored citrus fruit consisting of hybrids of mandarin orange varieties, with some pomelo contribution. The name was first used for fruit coming from Tangier, Morocco, described as a mandarin variety. Under the Tanaka classification system, ''Citrus tangerina'' is considered a separate species. Under the Swingle system, tangerines are considered a group of mandarin ('' C. reticulata'') varieties. Some differ only in disease resistance. The term is also currently applied to any reddish-orange mandarin (and, in some jurisdictions, mandarin-like hybrids, including some tangors). Tangerines are smaller and less ...

Citrus
''Citrus'' is a genus of flowering plant, flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as Orange (fruit), oranges, Lemon, lemons, grapefruits, pomelos, and lime (fruit), limes. The genus ''Citrus'' is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia (continent), Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion (c. 3000–1500 BCE); and to the Middle East and the Mediterranean (c. 1200 BCE) via the incense trade route, and onwards to Europe and the Americas. History Citrus plants are native to subtropical and tropical regions of Asia, Island Southeast Asia, Near Oceania, and northeastern Australia. Domestication of citrus species involved much hybridization and introgression, leaving much uncertainty ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
