Kirkiaceae
Kirkiaceae is a family of flowering plants in the order Sapindales. It comprises one (or two) genera, ''Kirkia'' (and '' Pleiokirkia'' now included in ''Kirkia''), totalling six species. These two genera were previously placed in family Simaroubaceae, but were transferred into their own family because they produce neither quassinoids nor limonoids. ''Kirkia'' is named for Captain John Kirk (explorer) of the famous Zambesi Expedition. They occur along the east coast of Africa, and in Madagascar Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Afric ....

Sapindales
Sapindales is an order of flowering plants. Well-known members of Sapindales include citrus; maples, horse-chestnuts, lychees and rambutans; mangos and cashews; frankincense and myrrh; mahogany and neem. The APG III system of 2009 includes it in the clade malvids (in rosids, in eudicots) with the following nine families: *Anacardiaceae * Biebersteiniaceae *Burseraceae * Kirkiaceae *Meliaceae * Nitrariaceae (including Peganaceae and Tetradiclidaceae) *Rutaceae *Sapindaceae * Simaroubaceae The APG II system of 2003 allowed the optional segregation of families now included in the Nitrariaceae. In the classification system of Dahlgren the Rutaceae were placed in the order Rutales, in the superorder Rutiflorae (also called Rutanae). The Cronquist system of 1981 used a somewhat different circumscription, including the following families: * Staphyleaceae * Melianthaceae *Bretschneideraceae * Akaniaceae *Sapindaceae * Hippocastanaceae * Aceraceae *Burseraceae *Anacardiaceae *Jul ...

Kirkia
''Kirkia'' is a genus of plant in family Kirkiaceae. It was previously placed in family Simaroubaceae, but was transferred into Kirkiaceae, together with '' Pleiokirkia'', because these genera produce neither quassinoids nor limonoids. The genus name of ''Kirkia'' is in honour of Sir John Kirk, (1832–1922), who was a physician, naturalist, companion to explorer David Livingstone, and British administrator in Zanzibar. Species It contains the following species (6), but this list may be incomplete): * '' Kirkia acuminata'' Oliv.

Simaroubaceae
The Simaroubaceae are a small, mostly tropical, family in the order Sapindales. In recent decades, it has been subject to much taxonomic debate, with several small families being split off. A molecular phylogeny of the family was published in 2007, greatly clarifying relationships within the family. Together with chemical characteristics such as the occurrence of petroselinic acid in ''Picrasma'', in contrast to other members of the family such as ''Ailanthus'', this indicates the existence of a subgroup in the family with ''Picrasma'', ''Holacantha'', and ''Castela''. The best-known species is the temperate Chinese tree-of-heaven '' Ailanthus altissima'', which has become a cosmopolitan weed tree of urban areas and wildlands. Well-known genera in the family include the tropical '' Quassia'' and ''Simarouba ''Simarouba'' is a genus of trees and shrubs in the family Simaroubaceae, native to the neotropics.

Angiosperm Phylogeny Group
The Angiosperm Phylogeny Group (APG) is an informal international group of systematic botanists who collaborate to establish a consensus on the taxonomy of flowering plants (angiosperms) that reflects new knowledge about plant relationships discovered through phylogenetic studies. , four incremental versions of a classification system have resulted from this collaboration, published in 1998, 2003, 2009 and 2016. An important motivation for the group was what they considered deficiencies in prior angiosperm classifications since they were not based on monophyletic groups (i.e., groups that include all the descendants of a common ancestor). APG publications are increasingly influential, with a number of major herbaria changing the arrangement of their collections to match the latest APG system. Angiosperm classification and the APG In the past, classification systems were typically produced by an individual botanist or by a small group. The result was a large number of systems ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Limonoid
Limonoids are phytochemicals of the triterpenoid class which are abundant in sweet or sour-scented citrus fruit and other plants of the families Cucurbitaceae, Rutaceae, and Meliaceae. Certain limonoids are antifeedants such as azadirachtin from the neem tree.{{cite journal, title=Biological activity of limonoids from the rutales, journal=Phytochemistry, volume=31, pages=377–394, authors=Donald E.Champagne, Opender Koul, Murray B. Isman, Geoffrey G. E.Scudder, G. H. Neil Towers, year=1992, issue=2, doi=10.1016/0031-9422(92)90003-9 Chemically, the limonoids consist of variations of the furanolactone core structure. The prototypical structure consists of four six-membered rings and a furan ring. Limonoids are classed as tetranortriterpenes. Citrus fruits contain the limonoids limonin, nomilin and nomilinic acid, while both neem seeds and leaves contain the limonoid azadirachtin, although higher concentrations are present in the former.
