Allamanda Cathartica
''Allamanda cathartica'', commonly called golden trumpet, common trumpetvine, and yellow allamanda, is a species of flowering plant in the family Apocynaceae. It is native to Bolivia, Brazil, French Guiana, Guyana, Suriname, and Venezuela, and widely naturalisation (biology), naturalised elsewhere in the tropics. This plant is cited in ''Flora Brasiliensis'' by Carl Friedrich Philipp von Martius. It does not twine, nor does it have tendrils or aerial roots. It can be pruned into a shrub form. If not pruned it can sprawl to a height of . According to McMullen, it can be up to in length in the Galapagos Islands where it is naturalised. The city of Canóvanas, Puerto Rico has adopted this species, known locally as ''canario amarillo'', as its official flower. Cultivation The species is cultivated as a house plant. It requires a soil rich in organic matter, temperatures of not less than during the growing season, plenty of moisture, and bright light but not direct sunlight. Durin ...

Apocynaceae
Apocynaceae (, from '' Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Notable members of the family include oleander, dogbanes, milkweeds, and periwinkles. The family is native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members as well. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here. Many species are tall trees found in tropical forests, but some grow in tropical dry ( xeric) environments. Also perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter oft ...

Vine
A vine is any plant with a growth habit of trailing or scandent (that is, climbing) stems, lianas, or runners. The word ''vine'' can also refer to such stems or runners themselves, for instance, when used in wicker work.Jackson; Benjamin; Daydon (1928). ''A Glossary of Botanic Terms with their Derivation and Accent'', 4th ed. London: Gerald Duckworth & Co. In parts of the world, including the British Isles, the term "vine" usually applies exclusively to grapevines, while the term "climber" is used for all climbing plants. Growth forms Certain plants always grow as vines, while a few grow as vines only part of the time. For instance, poison ivy and bittersweet can grow as low shrubs when support is not available, but will become vines when support is available. A vine displays a growth form based on very long stems. This has two purposes. A vine may use rock exposures, other plants, or other supports for growth rather than investing energy in a lot of supportive tissu ...

Frédéric-Louis Allamand
Frédéric-Louis Allamand (February 5, 1736, Payerne, Vaud – March 3, 1809, Valkenburg, South Holland) was a Swiss botanist. Born in Payerne, Switzerland, he moved to Leiden, Netherlands in 1749 to live with his uncle, Jean-Nicolas-Sébastien Allamand (1713–1787), a professor in philosophy and mathematics at Leiden University, well known naturalist, member of the Royal Society and correspondent of Benjamin Franklin. Frédéric started to study literature at the university of Leiden, however later changed to study medicine. In 1760 he joined the Dutch marine as a ship's doctor. During his time at the marine he visited among other places Suriname and Guyana. In 1769, he married Adriana van Guericke in Brielle. Algemeen Nederlandsch Familienblad. volume 13. page 248. 1900. Afterwards he became doctor at Catherine the Great's court in St. Petersburg. In 1793 he returned to Leiden to work at the university. He was a correspondent of Carl Linnaeus, and described several plant genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allemanda Neriifolia 12
An ''allemande'' (''allemanda'', ''almain(e)'', or ''alman(d)'', French: "German (dance)") is a Renaissance and Baroque dance, and one of the most common instrumental dance styles in Baroque music, with examples by Couperin, Purcell, Bach and Handel. It is often the first movement of a Baroque suite of dances, paired with a subsequent courante, though it is sometimes preceded by an introduction or prelude. Along with the waltz and ländler, the allemande was sometimes referred to by the generic term German Dance in publications during the late 18th and early 19th centuries. A quite different, later, Allemande, named as such in the time of Mozart and Beethoven, still survives in Germany and Switzerland and is a lively triple-time social dance related to the waltz and the ''Ländler''.Scholes P., 1970, article: ''Allemande''. The name "Allemande" comes from the name of Germany in French. History The allemande originated in the 16th century as a duple metre dance of moder ...

Iridoid
Iridoids are a type of monoterpenoids in the general form of cyclopentanopyran, found in a wide variety of plants and some animals. They are biosynthetically derived from 8-oxogeranial. Iridoids are typically found in plants as glycosides, most often bound to glucose. The chemical structure is exemplified by iridomyrmecin, a defensive chemical produced by the ant genus '' Iridomyrmex'', for which iridoids are named. Structurally, they are bicyclic ''cis''-fused cyclopentane-pyrans. Cleavage of a bond in the cyclopentane ring gives rise to a subclass known as ''secoiridoids'', such as oleuropein and amarogentin. Occurrence The iridoids produced by plants act primarily as a defense against herbivores or against infection by microorganisms. The variable checkerspot butterfly also contains iridoids obtained through its diet which act as a defense against avian predators. To humans and other mammals, iridoids are often characterized by a deterrent bitter taste. Aucubin and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lactone
Lactones are cyclic carboxylic esters. They are derived from the corresponding hydroxycarboxylic acids by esterification. They can be saturated or unsaturated. Lactones are formed by lactonization, the intramolecular esterification of the corresponding hydroxycarboxylic acids. Nomenclature Greek alphabet#Letters, Greek prefixes in alphabetical order indicate ring size. Lactones are usually named according to the precursor acid molecule (''aceto'' = 2 carbon atoms, ''propio'' = 3, ''butyro'' = 4, ''valero'' = 5, ''capro'' = 6, etc.), with a ''-lactone'' suffix and a Greek letter prefix that specifies the number of carbon atoms in the heterocycle — that is, the distance between the relevant -OH and the -COOH groups along said backbone. The first carbon atom after the carbon in the -COOH group on the parent compound is labelled α, the second will be labeled β, and so forth. Therefore, the prefixes also indicate the size of the lactone ring: α-lactone = 3-membered ring, β-lac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lignan
The lignans are a large group of low molecular weight polyphenols found in plants, particularly seeds, whole grains, and vegetables. The name derives from the Latin word for "wood". Lignans are precursors to phytoestrogens. They may play a role as antifeedants in the defense of seeds and plants against herbivores. Biosynthesis and metabolism Lignans and lignin differ in their molecular weight, the former being small and soluble in water, the latter being high polymers that are undigestable. Both are polyphenolic substances derived by oxidative coupling of monolignols. Thus, most lignans feature a C18 cores, resulting from the dimerization of C9 precursors. The coupling of the lignols occurs at C8. Eight classes of lignans are: "furofuran, furan, dibenzylbutane, dibenzylbutyrolactone, aryltetralin, arylnaphthalene, dibenzocyclooctadiene, and dibenzylbutyrolactol." Many lignans are metabolized by mammalian gut microflora, producing so-called enterolignans. Food sources Fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NF-κB
Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) is a family of transcription factor protein complexes that controls transcription (genetics), transcription of DNA, cytokine production and cell survival. NF-κB is found in almost all animal cell types and is involved in cellular responses to stimuli such as stress, cytokines, free radicals, heavy metals, ultraviolet irradiation, oxidized LDL, and bacterial or viral antigens. NF-κB plays a key role in regulating the immune response to infection. Incorrect regulation of NF-κB has been linked to cancer, inflammatory and autoimmune diseases, septic shock, viral infection, and improper immune development. NF-κB has also been implicated in processes of synaptic plasticity and memory. Discovery NF-κB was discovered by Ranjan Sen in the lab of Nobel laureate David Baltimore via its interaction with an 11-base pair sequence in the immunoglobulin light-chain Enhancer (genetics), enhancer in B cells.

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 Etymology The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively, the sepals are called the ''calyx'' (plural: calyces), the outermost Whorl (botany), whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. The Latin ''calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet'; both words have been used interchangeably in botanical Latin. Description The term ''tepal'' is usually applied when the parts of the perianth are difficult to distinguish, e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinoresinol
Pinoresinol is a tetrahydrofuran lignan found in '' Styrax sp.'', '' Forsythia suspensa, and in Forsythia koreana''. It is also found in the caterpillar of the cabbage butterfly, '' Pieris rapae'' where it serves as a defence against ants. In food, it is found in sesame seed, in '' Brassica'' vegetables and in olive oil. Pinoresinol has also been found to be toxic to larvae of the milkweed bug '' Oncopeltus fasciatus'' and of the haematophagous insect '' Rhodnius prolixus'', which is a vector of chagas disease. Currently, pinoresinol is isolated from plants with low efficiency and low yield. Biosynthesis A first dirigent protein was discovered in '' Forsythia intermedia''. This protein has been found to direct the stereoselective biosynthesis of (+)-pinoresinol from coniferyl alcohol monomers. Recently, a second, enantiocomplementary dirigent protein was identified in ''Arabidopsis thaliana'', which directs enantioselective synthesis of (-)-pinoresinol. Pharmacology Pi ...
