Anadenanthera Peregrina
''Anadenanthera peregrina'', also known as yopo, jopo, cohoba, parica or calcium tree, is a perennial tree of the genus ''Anadenanthera'' native to the Caribbean and South America. It grows up to tall, and has a horny bark. Its flowers grow in small, pale yellow to white spherical clusters resembling Acacia (e.g. wattle) inflorescences. It is an entheogen which has been used in healing ceremonies and rituals for thousands of years in northern South America and the Caribbean. Although the seeds of the yopo tree were originally gathered from the wild, increased competition between tribes over access to the seeds led to it being intentionally cultivated and transported elsewhere, expanding the plant's distribution through introduction to areas beyond its original native range. Related species This plant is almost identical to that of a related tree, ''Anadenanthera colubrina'', commonly known as cebíl or vilca. The beans of ''A. colubrina'' have a similar chemical makeup as '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Janka Wood Hardness Rating
The Janka hardness test (; ), created by Austrian-born American researcher Gabriel Janka (1864–1932), measures the resistance of a sample of wood to denting and wear. It measures the force required to embed an steel ball halfway into a sample of wood. (The diameter was chosen to produce a circle with an area of 100 square millimeters ne square centimeter) A common use of Janka hardness ratings is to determine whether a species is suitable for use as flooring. For hardwood flooring, the test usually requires a sample with a thickness of at least 6–8 mm, and the most commonly used test is the ASTM D1037. When testing wood in lumber form, the Janka test is always carried out on wood from the tree trunk (known as the heartwood), and the standard sample (according to ASTM D143) is at 12% moisture content and clear of knots. The hardness of wood varies with the direction of the wood grain. Testing on the surface of a plank, perpendicular to the grain, is said to be of "side h ...

Tannin
Tannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids. The term ''tannin'' (from Anglo-Norman ''tanner'', from Medieval Latin ''tannāre'', from ''tannum'', oak bark) refers to the use of oak and other bark in tanning animal hides into leather. By extension, the term ''tannin'' is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with various macromolecules. The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation (acting as pesticides) and might help in regulating plant growth. The astringency from the tannins is what causes the dry and puckery feeling in the mouth following the consumption of unripened fruit, red wine or tea. Likewise, the destruction or modification of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

N-Methyltryptamine
''N''-Methyltryptamine (NMT) is a member of the substituted tryptamine chemical class and a natural product which is biosynthesized in the human body from tryptamine by certain N-methyltransferase enzymes, such as indolethylamine ''N''-methyltransferase. It is a common component in human urine. NMT is an alkaloid derived from L-tryptophan that has been found in the bark, shoots and leaves of several plant genera, including ''Virola'', ''Acacia'', ''Mimosa'', and ''Desmanthus''—often together with the related compounds ''N'',''N''-dimethyltryptamine (DMT) and 5-methoxy-''N'',''N''-dimethyltryptamine (5-MeO-DMT). Orally administered NMT appears to produce no psychoactive effects, likely as a result of extensive first-pass metabolism.Foye's principles of medicinal chemistry By William O. Foye, Thomas L. Lemke, David A. Williams However, it may become active upon combination with a MAOA inhibitor (MAOI). By vaporization NMT shows activity at 50–100 mg, with a duration o ...

Dimethyltryptamine
''N'',''N''-Dimethyltryptamine (DMT or ''N'',''N''-DMT, SPL026) is a substituted tryptamine that occurs in many plants and animals, including human beings, and which is both a derivative and a structural analog of tryptamine. It is used as a psychedelic drug and prepared by various cultures for ritual purposes as an entheogen. DMT has a rapid onset, intense effects, and a relatively short duration of action. For those reasons, DMT was known as the "business trip" during the 1960s in the United States, as a user could access the full depth of a psychedelic experience in considerably less time than with other substances such as LSD or psilocybin mushrooms. DMT can be inhaled, ingested, or injected and its effects depend on the dose, as well as the mode of administration. When inhaled or injected, the effects last a short period of time: about five to 15 minutes. Effects can last three hours or more when orally ingested along with a monoamine oxidase inhibitor (MAOI), such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leucoanthocyanin
Leucoanthocyanidin (flavan-3,4-diols) are colorless chemical compounds related to anthocyanidins and anthocyanins. Leucoanthocyanins can be found in ''Anadenanthera peregrina'' and in several species of ''Nepenthes'' including '' N. burbidgeae'', '' N. muluensis'', '' N. rajah'', '' N. tentaculata'', and '' N. × alisaputrana''. Such compounds include: * Leucocyanidin * Leucodelphinidin * Leucofisetinidin * Leucomalvidin * Leucopelargonidin * Leucopeonidin * Leucorobinetinidin * Melacacidin * Teracacidin from ''Acacia obtusifolia'' and ''Acacia maidenii'' heartwoods Leucoanthocyanidins have been demonstrated to be intermediates in anthocyanidin biosynthesis in flowers of '' Matthiola incana''. Bate-smith recommended in 1954 the use of the Forestal solvent for the isolation of leuco-anthocyanins. Metabolism Leucoanthocyanidin dioxygenase uses flavan-3,4-diols to produce 3-hydroxyanthocyanidins. The gene encoding the enzyme (PpLDOX) has been identif ...

Catechol
Catechol ( or ), also known as pyrocatechol or 1,2-dihydroxybenzene, is a toxic organic compound with the molecular formula . It is the ''ortho'' isomer of the three isomeric benzenediols. This colorless compound occurs naturally in trace amounts. It was first discovered by destructive distillation of the plant extract catechin. About 20,000 tonnes of catechol are now synthetically produced annually as a commodity organic chemical, mainly as a precursor to pesticides, flavors, and fragrances. Catechol occurs as feathery white crystals that are very rapidly soluble in water. Isolation and synthesis Catechol was first isolated in 1839 by Edgar Hugo Emil Reinsch (1809–1884) by distilling it from the solid tannic preparation catechin, which is the residuum of catechu, the boiled or concentrated juice of ''Mimosa catechu'' (''Acacia catechu''). Upon heating catechin above its decomposition point, a substance that Reinsch first named ''Brenz-Katechusäure'' (burned catechu acid) ...

Amine Oxide
In chemistry, an amine oxide, also known as an amine ''N''-oxide or simply ''N''-oxide, is a chemical compound that contains the functional group , a nitrogen-oxygen coordinate covalent bond with three additional hydrogen and/or substituent-group side chains attached to N. Sometimes it is written as →O or, incorrectly, as . In the strict sense, the term ''amine oxide'' applies only to oxides of tertiary amines. Sometimes it is also used for the analogous derivatives of primary and secondary amines. Examples of amine oxides include pyridine-''N''-oxide, a water-soluble crystalline solid with melting point 62–67 °C, and ''N''-methylmorpholine ''N''-oxide, which is an oxidant. Applications Amine oxides are surfactants commonly used in consumer products such as shampoos, conditioners, detergents, and hard surface cleaners. Alkyl dimethyl amine oxide (chain lengths C10–C16) is the most commercially used amine oxide. They are considered a high production volume class of ...

Bufotenin
Bufotenin (5-HO-DMT, bufotenine) is a tryptamine derivative - more specifically, a DMT derivative - related to the neurotransmitter serotonin. It is an alkaloid found in some species of toads (especially the skin), mushrooms and plants. The name bufotenin originates from the toad genus ''Bufo'', which includes several species of psychoactive toads, most notably ''Incilius alvarius'', that secrete bufotoxins from their parotoid glands. Bufotenin is similar in chemical structure to the psychedelics psilocin (4-HO-DMT), 5-MeO-DMT, and DMT, chemicals which also occur in some of the same fungus, plant, and animal species as bufotenin. Nomenclature Bufotenin (bufotenine) is also known by the chemical names 5-hydroxy-''N'',''N''-dimethyltryptamine (5-HO-DMT), ''N'',''N''-dimethyl-5-hydroxytryptamine, dimethyl serotonin, and mappine. History Bufotenin was isolated from toad skin, and named by the Austrian chemist Handovsky at the University of Prague during World War I. The struct ...

5-MeO-DMT
5-MeO-DMT (5-methoxy-''N'',''N''-dimethyltryptamine) or O-methyl-bufotenin is a psychedelic of the tryptamine class. It is found in a wide variety of plant species, and also is secreted by the glands of at least one toad species, the Colorado River toad. Like its close relatives DMT and bufotenin (5-HO-DMT), it has been used as an entheogen in South America. Slang terms include Five-methoxy, The power, and Toad venom. Chemistry 5-MeO-DMT was first synthesized in 1936, and in 1959 it was isolated as one of the psychoactive ingredients of '' Anadenanthera peregrina'' seeds used in preparing Yopo snuff. It was once believed to be a major component of the psychoactive effects of the snuff, although this has recently been shown to be unlikely, due to the limited or sometimes even non-existent quantity contained within the seeds, which instead achieve their psychoactivity from the ''O''-demethylated metabolite of 5-MeO-DMT, bufotenin. It is metabolized mainly by CYP2D6. Effects D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
