Cocum
''Allophylus edulis'' ( pt, chal-chal) is a plant species in the genus ''Allophylus'' endemic to the Guianas, Brazil, Bolivia, Paraguay, Argentina and Uruguay. Phytochemistry Quebrachitol, a cyclitol, and viridiflorol, a sesquiterpenoid Sesquiterpenes are a class of terpenes that consist of three isoprene units and often have the molecular formula C15H24. Like monoterpenes, sesquiterpenes may be cyclic or contain rings, including many unique combinations. Biochemical modificati ..., are found in ''A. edulis''. Vernacular names This plant has several different common names. In Paraguay it's called ''kokû'', with a nasal ending. In Argentina, the common name is ''chal-chal'' (hence Los Chalchaleros, a folkloric music group), as in Portuguese.

Augustin Saint-Hilaire
Augustin François César Prouvençal de Saint-Hilaire (4 October 17793 September 1853) was French botanist and traveller who was born and died in Orléans, France. A keen observer, he is credited with important discoveries in botany, notably the direction of the radicle in the embryo sac and the double point of attachment of certain ovules. He also described two families, the Paronychiae and the Tamariscinae, as well as many genera and species. Biography He began to publish memoirs on botanical subjects at an early age. Between 1816 and 1822 and again in 1830, he traveled in South America, especially in south and central Brazil, and the results of his study of the rich flora of the regions through which he passed appeared in several books and numerous articles in scientific journals. In his first voyage, from 1816 to 1822, he explored the Brazilian backlands, traveling ca. 9,000 km, from Southeast Brazil to Río de la Plata, including the former Cisplatina Province (Urugua ...

Ludwig Adolph Timotheus Radlkofer
Ludwig Adolph Timotheus Radlkofer (19 December 1829, in Munich – 16 February 1927, in Munich), was a Bavarian taxonomist and botanist. Radlkofer became a physician in 1854 and earned a PhD in botany at Jena the following year. He became an associate professor of botany at the University of Munich in 1859 as well as deputy director of the botanical garden and herbarium. In 1892 he was named director of the Botanical Museum. He was made emeritus professor in 1913 and died in 1927 in the same room in which he was born. Radlkofer's main work was on the family Sapindaceae. His collections, sent by botanists from all over the world, are housed in Munich. The South African flower ''Greyia radlkoferi'' is named for him, as are the South American based genera of '' Radlkoferotoma'', and '' Radlkofera'', a monotypic genus of flowering plants from Africa belonging to the family Sapindaceae. The former genus ''Radlkoferella'' (a wastebasket genus) is now called ''Pouteria'',. Publishe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paraguay
Paraguay (; ), officially the Republic of Paraguay ( es, República del Paraguay, links=no; gn, Tavakuairetã Paraguái, links=si), is a landlocked country in South America. It is bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest. It has a population of seven million, nearly three million of whom live in the capital and largest city of Asunción, and its surrounding metro. Although one of only two landlocked countries in South America (Bolivia is the other), Paraguay has ports on the Paraguay and Paraná rivers that give exit to the Atlantic Ocean, through the Paraná-Paraguay Waterway.

Quebrachitol
Quebrachitol is a naturally occurring optically active cyclitol, a cyclic polyol. It can be found in ''Allophylus edulis'' and in the serum left after the coagulation of the ''Hevea brasiliensis'' latex in the operation of rubber tapping. It is also found in ''Cannabis sativa'', in ''Paullinia pinnata'' and in seabuckthorn. It was first isolated by Tanret in 1887 from the bark of ''Aspidosperma quebracho''. The substance was tested as a sweetening agent for diabetics in 1933. It shows a sweetening property half of that of sucrose but induces colic or diarrhoea Diarrhea, also spelled diarrhoea, is the condition of having at least three loose, liquid, or watery bowel movements each day. It often lasts for a few days and can result in dehydration due to fluid loss. Signs of dehydration often begin wi ... at concentration used to render the food palatable.

Cyclitol
In organic chemistry, a cyclitol is a cycloalkane containing at least three hydroxyl, each attached to a different ring carbon atom. The general formula for an unsubstituted cyclitol is or where 3 ≤ ''x'' ≤ ''n''. The name is also used for compounds that can be viewed as result of substituting various functional groups for the hydrogen atoms in such a molecule, as well as similar molecules with one or more double bonds in the ring. Cyclitols and their derivatives are some of the compatible solutes which are formed in a plant as a response to salt or water stress. Some cyclitols (e.g. quinic or shikimic acid) are parts of hydrolysable tannins. Isomerism and nomenclature Unsubstituted cyclitols with the same ring size and number of hydroxyls may exist in several structural isomers, depending on the position of the hydroxyls along the ring. For example, cyclohexanetriol exists in three distinct isomers (1,2,3-, 1,2,4-, and 1,3,5-). Furthermore, the hydrogen and the hydroxyl ...
