Saskatoon Berries
''Amelanchier alnifolia'', the saskatoon berry, Pacific serviceberry, western serviceberry, western shadbush, or western juneberry, is a shrub native to North America. It is a member of the rose family, and bears an edible berry-like fruit. Description It is a deciduous shrub or small tree that most often grows to , rarely to , in height. Its growth form spans from suckering and forming colonies to clumped. The leaves are oval to nearly circular, long and broad, on a leaf stem, with margins toothed mostly above the middle. As with all species in the genus ''Amelanchier'', the flowers are white, with five quite separate petals and five sepals. In ''A. alnifolia'', they are about across, with 20 stamens and five styles, appearing on short racemes of 3–20, somewhat crowded together, blooming from April to July. The fruit is a small purple pome in diameter, ripening in early summer. It has a waxy bloom. Saskatoon species can be relatively difficult to distinguish. ...

Polyphenol
Polyphenols () are a large family of naturally occurring phenols. They are abundant in plants and structurally diverse. Polyphenols include phenolic acids, flavonoids, tannic acid, and ellagitannin, some of which have been used historically as dyes and for tanning (leather), tanning garments. Etymology The name derives from the Ancient Greek word (, meaning "many, much") and the word ‘phenol’ which refers to a chemical structure formed by attachment of an aromatic benzenoid (phenyl) ring to a hydroxyl (-OH) group (hence the ''-ol'' suffix). The term "polyphenol" has been in use at least since 1894. Definition Polyphenols are natural products with "one or several hydroxyl groups on aromatic rings", including four principal classes: phenolic acids, flavonoids, stilbenes, and lignans. Flavonoids can be grouped as flavones, flavonols, flavanols, flavanones, isoflavones, proanthocyanidins, and anthocyanins. Particularly abundant flavanoids in foods are catechin (tea, frui ...

Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in ) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, ''Escobaria vivipara'', is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. Definitions The term is defined in different ways by different authors. However, the International Code of Nomenclature for Cultivated Plants, while recognizing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malvidin
Malvidin is an O-methylated anthocyanidin, the 3',5'-methoxy derivative of delphinidin. As a primary plant pigment, its glycosides are highly abundant in nature. Natural occurrences Malvidin is responsible for the blue color found in petals of the '' Primula'' plants of the ''polyanthus'' group. Blue flowers of the blue pimpernel ('' Anagallis monelli'') have also a higher concentration of malvidin. It is responsible primarily for the color of red wine, ''Vitis vinifera'' being one of its sources. It is also present in other berries, such as blueberries ('' Vaccinium corymbosum'') or the saskatoon berries ('' Amelanchier alnifolia''). Chemistry Slightly acidic and neutral solutions of malvidin are characteristically of a red color, while basic solutions of malvidin yield a blue color. The breakdown of malvidin releases syringic acid. Use as a marker in archaeology The breakdown of malvidin releases syringic acid as revealed in the examination of jars containing she ...

Peonidin
Peonidin is an O-methylated anthocyanidin derived from Cyanidin, and a primary plant pigment. Peonidin gives purplish-red hues to flowers such as the peony, from which it takes its name, and roses. It is also present in some blue flowers, such as the morning glory. Like most anthocyanidins, it is pH sensitive, and changes from red to blue as pH rises because anthocyanidins are highly conjugated chromophores. When the pH is changed, the extent of the conjugation (of the double bonds) is altered, which alters the wavelength of light energy absorbed by the molecule. (Natural anthocyanidins are most stable in a very low pH environment; at pH 8.0, most become colorless.) At pH 2.0, peonidin is cherry red; at 3.0 a strong yellowish pink; at 5.0 it is grape red-purple; and at 8.0 it becomes deep blue; unlike many anthocyanidins, however, it is stable at higher pH, and has been isolated as a blue colorant from the brilliant "Heavenly Blue" morning glory (''Ipomoea tricolor Cav cv'').

Petunidin
Petunidin (Pt), like Europinidin and Malvidin, is derived from Delphinidin and is an O-methylated anthocyanidin of the 3-hydroxy type. It is a natural organic compound, a dark-red or purple water-soluble pigment found in many red berries including chokeberries ('' Aronia sp''), Saskatoon berries ('' Amelanchier alnifolia'') or different species of grape (for instance ''Vitis vinifera'', or muscadine, ''Vitis rotundifolia''), and also part of the pigments responsible for the petal colors in many flowers. This pigment gives the Indigo Rose tomatoes the majority of their deep purple color when the fruits are exposed to sunlight. The name of the molecule itself is derived from the word Petunia. Biosynthesis Petunidin could form in the exocarp of fruits from delphinidin, with an anthocyanin flavonoid O-methyltransferase (Catechol-O-methyl transferase) catalyzing the B-ring methylation and S-Adenosyl-L-methyl-3H methionine being the methyl group donor.

Pelargonidin
Pelargonidin is an anthocyanidin, a type of plant pigment producing a characteristic orange color used in food and industrial dyes. Natural occurrences Presence in flowers Pelargonidin can be found in red geraniums (Geraniaceae). It is the predominant pigment causing the red coloration in the spathes of ''Philodendron'' (Araceae). The orange-coloured flowers of blue pimpernel (''Anagallis monelli'', Myrsinaceae) have a higher concentration of pelargonidin pigment. Red and Pink Roses (Rosa) obtain their color from this phytochemical. Presence in food Pelargonidin can be found in berries such as ripe Raspberry, raspberries and Strawberry, strawberries, as well as Blueberry, blueberries, Blackberry, blackberries, Cranberry, cranberries but also in saskatoon berries and chokeberries. It is also found in plums and pomegranates. Pelargonidin gives red radish, radishes their color. It is present in large amounts in kidney beans. Glycosides In many plant systems, Pelargonidin c ...

Delphinidin
Delphinidin (also delphinidine) is an anthocyanidin, a primary plant pigment, and also an antioxidant. Delphinidin gives blue hues to flowers in the genera ''Viola'' and ''Delphinium''. It also gives the blue-red color of the grape variety Cabernet Sauvignon, and can be found in cranberries and Concord grapes as well as pomegranates, and bilberries. Delphinidin, like nearly all other anthocyanidins, is pH-sensitive, i.e. a natural pH indicator, and changes from blue in basic solution to red in acidic solution. Glycosides Several glycosides derived from delphinidin are known: * Myrtillin (delphinidin-3-''O''-glucoside) and tulipanin (delphinidin-3-''O''-rutinoside) can be found in blackcurrant pomace. * Violdelphin (delphinidin 3-rutinoside-7-''O''-(6-''O''-(4-(6-''O''-(4-hydroxybenzoyl)-β-D-glucosyl)oxybenzoyl)-β-D-glucoside) is responsible for the purplish-blue flower color of '' Aconitum chinense''. * Nasunin (delphinidin-3-(''p''-coumaroylrutinoside)-5-glucosid ...

Cyanidin
Cyanidin is a natural organic compound. It is a particular type of anthocyanidin (glycoside version called anthocyanin#Structure, anthocyanins). It is a pigment found in many red berries including grapes, bilberry, blackberry, blueberry, cherry, chokeberry, cranberry, elderberry, Crataegus, hawthorn, loganberry, açai berry and raspberry. It can also be found in other fruits such as apples and plums, and in red cabbage and red onion. It has a characteristic reddish-purple color, though this can change with pH; solutions of the compound are red at pH 11. In certain fruits, the highest concentrations of cyanidin are found in the seeds and skin. Cyanidin has been found to be a potent sirtuin 6 (SIRT6) activator. List of cyanidin derivatives * Antirrhinin (cyanidin-3-rutinoside or 3-C-R), found in black raspberry * Cyanidin-3-xylosylrutinoside, found in black raspberry * Cyanidin-3,4′-di-''O''-β-glucopyranoside, found in red onion * Cyanidin-4′-''O''-β-glucoside, found in ...

Quercetin
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 ...
