Plantae
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angiosperms
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 are in the ...

Eudicots
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants mainly characterized by having two seed leaves upon germination. The term derives from Dicotyledons. Traditionally they were called tricolpates or non-magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Some common and familiar eudicots include sunflower, dandelion, forget-me-not, cabbage, apple, buttercup, maple, and macadamia. Most leafy trees of midlatitudes also belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, and ''Ginkgo biloba'', which is not an angiosperm.

Rosids
The rosids are members of a large clade (monophyletic group) of flowering plants, containing about 70,000 species, more than a quarter of all angiosperms. The clade is divided into 16 to 20 orders, depending upon circumscription and classification. These orders, in turn, together comprise about 140 families. Fossil rosids are known from the Cretaceous period. Molecular clock estimates indicate that the rosids originated in the Aptian or Albian stages of the Cretaceous, between 125 and 99.6 million years ago. Today's forests are highly dominated by rosid species, which in turn helped with diversification in many other living lineages. Additionally, rosid herbs and shrubs are also a significant part of arctic/alpine, temperate floras, aquatics, desert plants, and parasites. Name The name is based upon the name "Rosidae", which had usually been understood to be a subclass. In 1967, Armen Takhtajan showed that the correct basis for the name "Rosidae" is a description of a group of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fabales
The Fabales are an order (biology), order of flowering plants included in the Rosids, rosid group of the eudicots in the APG II system, Angiosperm Phylogeny Group II classification system. In the APG II circumscription, this order includes the families Fabaceae or legumes (including the subfamilies Caesalpinioideae, Mimosoideae, and Faboideae), Quillajaceae, Polygalaceae or milkworts (including the families Diclidantheraceae, Moutabeaceae, and Xanthophyllaceae), and Surianaceae. Under the Cronquist system and some other plant classification systems, the order Fabales contains only the family Fabaceae. In the classification system of Rolf Dahlgren, Dahlgren the Fabales were in the superorder Fabiflorae (also called Fabanae) with three families corresponding to the subfamilies of Fabaceae in APG II. The other families treated in the Fabales by the APG II classification were placed in separate orders by Cronquist, the Polygalaceae within its own order, the Polygalales, and the Quill ...

Fabaceae
The Fabaceae or Leguminosae,International Code of Nomenclature for algae, fungi, and plants. Article 18.5 states: "The following names, of long usage, are treated as validly published: ....Leguminosae (nom. alt.: Fabaceae; type: Faba Mill. Vicia L.; ... When the Papilionaceae are regarded as a family distinct from the remainder of the Leguminosae, the name Papilionaceae is conserved against Leguminosae." English pronunciations are as follows: , and . commonly known as the legume, pea, or bean family, are a large and agriculturally important of |
Faboideae
The Faboideae are a subfamily of the flowering plant family Fabaceae or Leguminosae. An acceptable alternative name for the subfamily is Papilionoideae, or Papilionaceae when this group of plants is treated as a family. This subfamily is widely distributed, and members are adapted to a wide variety of environments. Faboideae may be trees, shrubs, or herbaceous plants. Members include the pea, the sweet pea, the laburnum, and other legumes. The pea-shaped flowers are characteristic of the Faboideae subfamily and root nodulation is very common. Genera The type genus, ''Faba'', is a synonym of ''Vicia'', and is listed here as ''Vicia''. *''Abrus'' *''Acmispon'' *''Acosmium'' *'' Adenocarpus'' *'' Adenodolichos'' *'' Adesmia'' *'' Aenictophyton'' *''Aeschynomene'' *'' Afgekia'' *''Aganope'' *'' Airyantha'' *''Aldina'' *''Alexa'' *''Alhagi'' *'' Alistilus'' *'' Almaleea'' *'' Alysicarpus'' *'' Amburana'' *''Amicia'' *'' Ammodendron'' *'' Ammopiptanthus'' *'' Ammothamnus'' *'' ...

Lonchocarpus
''Lonchocarpus'' is a plant genus in the legume family (biology), family (Fabaceae). The species are called lancepods due to their fruit resembling an ornate lance tip or a few beads on a string. ''Cubé'' resin is produced from the roots of ''Lonchocarpus urucu, L. urucu'' and namely 'Lonchocarpus utilis, L. utilis'' (''cubé''). It contains enough of the toxic rotenoids rotenone and deguelin to be used as an insecticide and piscicide. As these are naturally occurring compounds, they were formerly used in organic farming. Since it is highly unselective and kills useful, as well as pest, animals, it is considered harmful to the environment today. Also, Chronic (medicine), chronic exposure to rotenone and deguelin seems to increase the risk of Parkinson's disease even in mammals, for which these compounds are less Acute (medicine), acutely toxic than for fish and insects. On the other hand, deguelin might be useful in cancer therapy if it can be applied directly into tumors, and ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henri François Pittier
Henri François Pittier de Fabrega (August 13, 1857 in Bex, Switzerland – January 27, 1950 in Caracas, Venezuela) was a Swiss-born geographer and botanist who started Venezuelan National Park history. Biography He graduated as an engineer from the University of Jena and moved to Costa Rica in 1887, where he founded the Physical Geographic Institute and an herbarium. Pittier collected fungi in Costa Rica which was published as a paper in 1896 by Marietta Hanson Rousseau and Elisa Caroline Bommer, and collected spiders that were detailed or described by A. Getaz in a paper in 1893, and collected at various dates and locations in the prior four years. That latter work also mentions a specimen from Greytown (Nicaragua) also collected by H.Pittier. Pittier arrived in Venezuela in 1917, where he classified more than 30,000 plants and devoted many years to studying the flora and fauna in the country. Henri Pittier National Park was the first national park established in Venezue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotenoid
Rotenoids are naturally occurring substances containing a cis-fused tetrahydrochromeno ,4-bhromene nucleus. Many have insecticidal activity, such as the prototypical member of the family, rotenone. Rotenoids are related to the isoflavones. Natural occurrences Many plants in the subfamily Faboideae contain rotenoids. Rotenoids can be found in ''Lonchocarpus sp''. Deguelin and tephrosin can be found in ''Tephrosia vogelii''. 6'-O-β-D-glucopyranosyl-12a-hydroxydalpanol can be found in the fruits of ''Amorpha fruticosa''. Elliptol, 12-deoxo-12alpha-methoxyelliptone, 6-methoxy-6a,12a-dehydrodeguelin, 6a,12a-dehydrodeguelin, 6-hydroxy-6a,12a-dehydrodeguelin, 6-oxo-6a,12a-dehydrodeguelin and 12a-hydroxyelliptone can be isolated from the twigs of ''Millettia duchesnei''. Deguelin, dehydrodeguelin, rotenol, rotenone, tephrosin and sumatrol can be found in ''Indigofera tinctoria''. 6aα,12aα-12a-hydroxyelliptone can be found in the stems of ''Derris trifoliata''.

Deguelin
Deguelin is a derivative of rotenone. Both are compounds classified as rotenoids of the flavonoid family and are naturally occurring insecticides. They can be produced by extraction from several plant species belonging to three genera of the legume family, Fabaceae: ''Lonchocarpus'', ''Derris'', or ''Tephrosia''. Cubé resin, the root extract from cubé (''Lonchocarpus utilis'') and from barbasco (''Lonchocarpus urucu''), is used as a commercial insecticide and piscicide (fish poison). The major active ingredients are rotenone and deguelin. Although "organic" (produced by nature) cubé resin is no longer considered environmentally safe. Rat pharmacokinetics * Mean residence time (MRT) = 6.98 h * Terminal half-life (t1/2(gamma)) = 9.26 h * Area under the curve (AUC) = 57.3 ng h/ml * Total clearance (Cl) = 4.37 L/h per kg * Apparent volume of distribution (V) = 3.421 L/kg * Volume of distribution at steady-state (Vss) = 30.46 L/kg * Tissue distributions after i.v.

Rotenone
Rotenone is an odorless, colorless, crystalline isoflavone used as a broad-spectrum insecticide, piscicide, and pesticide. It occurs naturally in the seeds and stems of several plants, such as the jicama vine plant, and the roots of several members of Fabaceae. It was the first described member of the family of chemical compounds known as rotenoids. Discovery The earliest record of the now-known rotenone-containing plants used for killing leaf-eating caterpillars was in 1848, and for centuries, the same plants were used to poison fish. The active chemical component was first isolated in 1895 by a French botanist, Emmanuel Geoffroy, who called it ''nicouline'', from a specimen of ''Robinia nicou'', now called ''Lonchocarpus nicou'', while traveling in French Guiana. He wrote about this research in his thesis, published in 1895 after his death from a parasitic disease. In 1902 Kazuo Nagai, Japanese chemical engineer of the Government-General of Taiwan, isolated a pure crystalline ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
