Quassia Indica
''Quassia'' ( or ) is a plant genus in the family Simaroubaceae. Its size is disputed; some botanists treat it as consisting of only one species, ''Quassia amara'' from tropical South America, while others treat it in a wide circumscription as a pantropical genus containing up to 40 species of trees and shrubs. The genus was named after a former slave from Suriname, Graman Quassi in the eighteenth century. He discovered the medicinal properties of the bark of ''Quassia amara''. Distribution Members of the genus are found in the Tropics throughout the world. Countries and regions where species are native include: Andaman Islands, Angola, Bangladesh, Belize, Benin, Bismarck Archipelago, Borneo, North and Northeast Brazil, Burkina, Cabinda, Cambodia, Cameroon, Central African Republic, Chad, Colombia, Comoros, Congo, Costa Rica, El Salvador, Equatorial Guinea, Gabon, Gambia, Ghana, Guatemala, Guinea, Guinea-Bissau, Gulf of Guinea Islands, Honduras, India, Ivory Coast, Kenya, Laos, L ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quassin
Quassin is a white, bitter, crystalline substance that is the prototypical example of the family of quassinoids. It can be extracted from the quassia tree, from which it gets its name. It was first isolated in 1937 and its chemical structure was elucidated in 1961. It is one of the most bitter substances found in nature, with a bitter threshold of 0.08 ppm and it is 50 times more bitter than quinine.Scientific Committee on FooOpinion of the Scientific Committee on Food on quassin (expressed on 2 July 2002). SCF/CS/FLAV/FLAVOUR/29 Final Extracts of the bitterwood tree (''Quassia amara'') containing quassin are used as additives in soft drinks. Although its skeleton possesses 20 carbon atoms, quassin is not a diterpene but rather a triterpene lactone Lactones are cyclic carboxylic esters, containing a 1-oxacycloalkan-2-one structure (), or analogues having unsaturation or heteroatoms replacing one or more carbon atoms of the ring.

Quassinoid
Quassinoids are degraded triterpene lactones (similar to limonoids) of the Simaroubaceae plant family grouped into C-18, C-19, C-20, C-22 and C-25 types. The prototypical member of the group, quassin, was first described in the 19th century from plants of the genus '' Quassia'' from which it gets its name. It was isolated in 1937 and its structure elucidated in 1961. They are a biologically potent class of natural products, possessing antimalarial, antifeedant, insecticidal, anti-inflammatory, and anticancer properties. The quassinoid bruceantin reached two separate phase II clinical trials in 1982 and 1983. Other quassinoids include: * Bruceanols * Bruceolide * Eurycomanone * Gutolactone Gutolactone is a chemical compound A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds.

Quassia Harmandiana
''Quassia harmandiana'' is a freshwater mangrove shrub or small tree in the Simaroubaceae family. It is found in Cambodia, Laos and Vietnam. The wood provides firewood. Certain fish eat the poisonous fruit Description This species grows as a shrub or small tree, some 5 to 8m tall. The species was placed in the section Samadera by Noteboom, along with '' Quassia indica''. The plants of this section have simple leaves with roughly scattered concave glands, mostly on the under surface. The flowers are bisexual, occurring in axillary or terminal inflorescences, either pseudoumbels with peduncles or in racemes. There are 3-5 calyx lobes, these are imbricate in the bud, obtuse and have a concave gland in the centre. There are 3-5 contorted petals, much longer than the calyx, usually hairy on the underside. The disc is large, as high as it is broad, and gynophore-like. The style has a inconspicuous terminal stigma. The quite large fruits are compressed laterally, with a narrow, thinne ...
