Punicalagin
Punicalagin is an ellagitannin, a type of phenolic compound. It is found as alpha and beta isomers in pomegranates (''Punica granatum''), ''Terminalia catappa'', ''Terminalia myriocarpa'', and in ''Combretum molle'', the velvet bushwillow, a plant species found in South Africa. These three genera are all Myrtales and the last two are both Combretaceae. Research Punicalagins are water-soluble and hydrolyze into smaller phenolic compounds, such as ellagic acid Ellagic acid is a polyphenol found in numerous fruits and vegetables. It is the dilactone of hexahydroxydiphenic acid. Name The name comes from the French term ''acide ellagique'', from the word ''galle'' spelled backwards because it can be ....

Pomegranate Ellagitannins
The pomegranate ellagitannins, which include punicalagin isomers, are ellagitannins found in the sarcotestas, rind (peel), bark or heartwood of pomegranates (''Punica granatum''). Chemistry As the chemistry of punicalagins became known it was found to be not unique to pomegranate. Punicalagins are present in numerous species of the genus '' Terminalia'', species '' chebula'' Retz. (“Fructus Chebulae”), '' myriocarpa'', '' catappa'' and citrina (tropical flowering trees historically used in African traditional medicine for antibiotic and antifungal purposes). They have also been isolated from '' Cistus salvifolius'' (a Mediterranean shrub) and ''Combretum molle'' (an African shrub). Pomegranate fruits natural phenols can be extracted with ethyl acetate and fractionation can afford the ellagitannin punicalagins. Dietary supplementation A few dietary supplements and nutritional ingredients are available that contain extracts of whole pomegranate and/or are standardized to p ...

Ellagitannin
The ellagitannins are a diverse class of hydrolyzable tannins, a type of polyphenol formed primarily from the oxidative linkage of galloyl groups in 1,2,3,4,6-pentagalloyl glucose. Ellagitannins differ from gallotannins, in that their galloyl groups are linked through C-C bonds, whereas the galloyl groups in gallotannins are linked by depside bonds. Ellagitannins contain various numbers of hexahydroxydiphenoyl units, as well as galloyl units and/or sanguisorboyl units bounded to sugar moiety. In order to determine the quantity of every individual unit, the hydrolysis of the extracts with trifluoroacetic acid in methanol/water system is performed. Hexahydroxydiphenic acid, created after hydrolysis, spontaneously lactonized to ellagic acid, and sanguisorbic acid to sanguisorbic acid dilactone, while gallic acid remains intact. Ellagitannins generally form macrocycles, whereas gallotannins do not. Examples * Castalagin * Castalin * Casuarictin * Grandinin * Oeno ...

Phenolic Compound
In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (— O H) bonded directly to an aromatic hydrocarbon group. The simplest is phenol, . Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule. Phenols are both synthesized industrially and produced by plants and microorganisms. Properties Acidity Phenols are more acidic than typical alcohols. The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids (their pKa is usually between 10 and 12). Deprotonation of a phenol forms a corresponding negative phenolate ion or phenoxide ion, and the corresponding salts are called phenolates or phenoxides (aryloxides according to the IUPAC Gold Book). Condensation with aldehydes and ketones Phenols are susceptible to Electrophilic aromatic substitutions. Condensation with fo ...

Pomegranate
The pomegranate (''Punica granatum'') is a fruit-bearing deciduous shrub in the family Lythraceae, subfamily Punicoideae, that grows between tall. The pomegranate was originally described throughout the Mediterranean Basin, Mediterranean region. It was introduced into Spanish America in the late 16th century and into California by New Spain, Spanish settlers in 1769. The fruit is typically in season in the Southern Hemisphere from March to May, and in the Northern Hemisphere from September to February. As intact sarcotestas or juice, pomegranates are used in baking, cooking, juice blends, meal garnish (food), garnishes, smoothies, and alcoholic beverages, such as cocktails and wine. Pomegranates are widely cultivated throughout the Middle East and Caucasus region, North Africa, north and tropical Africa, Iran, Armenia, the Indian subcontinent, Central Asia, the drier parts of Southeast Asia, and the Mediterranean Basin.

Terminalia Catappa
''Terminalia catappa'' is a large tropical tree in the leadwood tree family, Combretaceae, native to Asia, Australia, the Pacific, Madagascar and Seychelles. Common names in English include country almond, Indian almond, Malabar almond, sea almond, tropical almond, beach almond and false kamani. Description The tree grows to tall, with an upright, symmetrical crown and horizontal branches. The fruit are corky and light, and dispersed by water. As the tree gets older, its crown becomes more flattened to form a spreading, vase shape. Its branches are distinctively arranged in tiers. The leaves are large, long and broad, ovoid, glossy dark green, and leathery. They are dry-season deciduous; before falling, they turn pinkish-reddish or yellow-brown, due to pigments such as violaxanthin, lutein, and zeaxanthin. The trees are monoecious, with distinct male and female flowers on the same tree. Both are in diameter, white to greenish, inconspicuous with no petals; they are produced ...

Hydrolyze
Hydrolysis (; ) is any chemical reaction in which a molecule of water breaks one or more chemical bonds. The term is used broadly for substitution, elimination, and solvation reactions in which water is the nucleophile. Biological hydrolysis is the cleavage of biomolecules where a water molecule is consumed to effect the separation of a larger molecule into component parts. When a carbohydrate is broken into its component sugar molecules by hydrolysis (e.g., sucrose being broken down into glucose and fructose), this is recognized as saccharification. Hydrolysis reactions can be the reverse of a condensation reaction in which two molecules join into a larger one and eject a water molecule. Thus hydrolysis adds water to break down, whereas condensation builds up by removing water. Types Usually hydrolysis is a chemical process in which a molecule of water is added to a substance. Sometimes this addition causes both the substance and water molecule to split into two parts. In su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ellagic Acid
Ellagic acid is a polyphenol found in numerous fruits and vegetables. It is the dilactone of hexahydroxydiphenic acid. Name The name comes from the French term ''acide ellagique'', from the word ''galle'' spelled backwards because it can be obtained from ''noix de galle'' ( galls), and to distinguish it from ''acide gallique'' (gallic acid). The molecule structure resembles to that of two gallic acid molecules being assembled "head to tail" and bound together by a C–C bond (as in biphenyl, or in diphenic acid) and two lactone links (cyclic carboxylic esters). Metabolism Biosynthesis Plants produce ellagic acid from hydrolysis of tannins such as ellagitannin and geraniin. Biodegradation Urolithins are gut flora human metabolites of dietary ellagic acid derivatives. Ellagic acid has low bioavailability, with 90% remaining unabsorbed from the intestines until metabolized by microflora to the more bioavailable urolintins. History Ellagic acid was first discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
