δ-Cadinol
δ-Cadinol is an organic compound, a sesquiterpenoid alcohol produced by many plants as well as some animals and microorganisms. It is a white crystalline solid, soluble in isopropyl ether and ethanol. It is an epimer of α-cadinol. δ-Cadinol exists in nature as either of two enantiomers distinguished by the prefixes (+)- and (−)-.Lars Westfelt (1970), "(−)-Torryeol ('δ-Cadinol')". ''Acta Chemica Scandinavica'' volume 24 issue 5 16181622 The (+)-isomer was identified by E. Shinozaki in 1922 from the leaves of ''Torreya nucifera'' and originally named torreyol. The (−)-isomer was isolated in 1951 by Haagen-Smit and others from '' Pinus albicaulus'' and first called albicaulol. Its structure was determined in 1970 by Lars Westfelt. Other names were given to δ-cadinol based on its various biological sources before the structures were confirmed, including sesquigoyol for (+)-δ-cadinol and pilgerol for (−)-δ-cadinol. Lambertol is thought to be either (+)-δ-cadinol or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Achillea Millefolium
''Achillea millefolium'', commonly known as yarrow () or common yarrow, is a flowering plant in the family Asteraceae. Other common names include old man's pepper, devil's nettle, sanguinary, milfoil, soldier's woundwort, and thousand seal. The plant is native to temperate regions of the Northern Hemisphere in Asia, Europe, and North America. It has been introduced as a feed for livestock in New Zealand and Australia. Description ''Achillea millefolium'' is an erect, herbaceous, perennial plant that produces one to several stems in height, and has a spreading rhizomatous growth form. Leaves are evenly distributed along the stem, with the leaves near the middle and bottom of the stem being the largest. The leaves have varying degrees of hairiness (pubescence). The leaves are long, bipinnate or tripinnate, almost feathery, and arranged spirally on the stems. The leaves are cauline, and more or less clasping, being more petiolate near the base. The inflorescence has 4 to 9 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Organic Compound
In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive. Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living t ...

Pheromone
A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are ''alarm signal, alarm pheromones'', ''food trail pheromones'', ''sex pheromones'', and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology. Background The portmanteau word "pheromone" was coined by Peter Karlson and Martin Lüscher in 1959, based on the Greek φερω ''pheroo'' ('I carry') and ὁρμων ''hormon'' ('stimulating'). P ...

Butterfly
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the Order (biology), order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily (zoology), superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo Holometabolism, complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brown Alga
Brown algae (singular: alga), comprising the class (biology), class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. They are dominant on rocky shores throughout cooler areas of the world. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat. For instance, ''Macrocystis'', a kelp of the order Laminariales, may reach in length and forms prominent underwater kelp forests. Kelp forests like these contain a high level of biodiversity. Another example is ''Sargassum'', which creates unique floating mats of seaweed in the tropical waters of the Sargasso Sea that serve as the habitats for many species. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Some members of the class, such as kelps, are used by humans as food. Be ...

Copaiba
Copaiba is a stimulant oleoresin obtained from the trunk of several pinnate-leaved South American leguminous trees (genus ''Copaifera''). The thick, transparent exudate varies in color from light gold to dark brown, depending on the ratio of resin to essential oil. Copaiba is used in making varnishes and lacquers. The balsam may be steam distilled to give ''copaiba oil'', a colorless to light yellow liquid with the characteristic odor of the balsam and an aromatic, slightly bitter, pungent taste. The oil consists primarily of sesquiterpene hydrocarbons; its main component is β-caryophyllene. The oil also contains significant amounts of α-bergamotene, α-copaene, and β-bisabolene. Copaiba is also a common name for several species of trees of the legume family native to Tropical Africa and North and South America. Uses Copaiba is particularly interesting as a source of biodiesel, because of the high yield of . The resin is tapped from standing trees, with an individual ...

Copaifera Multijuga
''Copaifera'' is a genus of tropical plants in the legume family Fabaceae. The scientific name means "copal-bearer" (or more accurately, ''copaiba''-bearer), since economically important resins and essential oils can be acquired from them. They are also important for production of biodiesel and wood, especially ''Copaifera langsdorffii''. Other species are threatened, mainly by deforestation. Oil extracts from the genus are of particular interest as a source of antimycobacterial agents. Notable species *''Copaifera epunctata'' *'' Copaifera guyanensis'' *''Copaifera langsdorffii'' – Diesel tree, kerosene tree, kupa'y, cabismo, copaúva *''Copaifera martii'' *''Copaifera multijuga'' *''Copaifera officinalis'' *''Copaifera panamensis'' – Cabimo *''Copaifera reticulata'' *''Copaifera salikounda'' *''Copaifera trapezifolia'' *''Copaifera cearensis'' *''Copaifera jacquinii'' *''Copaifera coriacea'' See also *Copaene Copaene, or more precisely, α-copaene, is the common (or tr ...

Mushroom
A mushroom or toadstool is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground, on soil, or on its food source. ''Toadstool'' generally denotes one poisonous to humans. The standard for the name "mushroom" is the cultivated white button mushroom, ''Agaricus bisporus''; hence the word "mushroom" is most often applied to those fungi ( Basidiomycota, Agaricomycetes) that have a stem ( stipe), a cap ( pileus), and gills (lamellae, sing. lamella) on the underside of the cap. "Mushroom" also describes a variety of other gilled fungi, with or without stems, therefore the term is used to describe the fleshy fruiting bodies of some Ascomycota. These gills produce microscopic spores that help the fungus spread across the ground or its occupant surface. Forms deviating from the standard morphology usually have more specific names, such as "bolete", "puffball", "stinkhorn", and " morel", and gilled mushrooms themselves are often called "agarics" in refere ...
