Punica Granatum
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 region. It was introduced into Spanish America in the late 16th century and into California by 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 garnishes, smoothies, and alcoholic beverages, such as cocktails and wine. Pomegranates are widely cultivated throughout the Middle East and Caucasus region, north and tropical Africa, Iran, Armenia, the Indian subcontinent, Central Asia, the drier parts of Southeast Asia, and the Mediterranean Basin. Etymology The name pomegranate derives from medieval Latin "apple" and "seeded". Possibly stemming from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. There were no toxic effects in rats on a 6% diet of punicalagins for 37 days. In laboratory research, punicalagins had carbonic anhydrase inhibitor Carbonic anhydrase inhibitors are a class of pharmaceuticals that suppress the activity of carbonic anhydrase. Their clinical use has been established as anti-glaucoma agents, diuretics, antiepileptics, in the management of mountain sickness, ... activity.

Punicalin
Punicalin is an ellagitannin. It can be found in ''Punica granatum'' (pomegranate) or in the leaves of ''Terminalia catappa'', a plant used to treat dermatitis and hepatitis. It is also reported in ''Combretum glutinosum'', all three species being Myrtales, the two last being Combretaceae. It is a highly active carbonic anhydrase inhibitor. Chemistry The molecule contains a gallagic acid component linked to a glucose Glucose is a simple sugar with the molecular formula . Glucose is overall the most abundant monosaccharide, a subcategory of carbohydrates. Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using ....

Ellagitannins
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 * Oenothein B from ...
