Aztekium Ritteri
''Aztekium ritteri'' is a species of cactus, in the genus ''Aztekium''. It is one of the three species that make up the genus. The species originated in Mexico. Aztekium is a genus endemic to Mexico. In Mexico, Aztekium ritterii it is called “Peyotillo.” However, even though it contains ''N''-methyltyramine, hordenine, anhalidine, mescaline, pellotine, and 3-methoxytyramine 3-Methoxytyramine (3-MT), also known as 3-methoxy-4-hydroxyphenethylamine, is a human trace amine that occurs as a metabolite of the neurotransmitter dopamine. It is formed by the introduction of a methyl group to dopamine by the enzyme cate ..., there have been no ethnobotanical reports that state that it has ever been used by the indigenous people of the area. Blooming habits The ''Aztekium ritteri'' blooms throughout the summer, producing an abundance of white and pink flowers measuring less than one centimeter in diameter. These flowers are followed by small pink fruit that open when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cactus
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spine ...

Aztekium
The genus ''Aztekium'' contains three species of small globular cactus. Discovered in 1929 by F. Ritter, in Rayones, Nuevo León, Mexico, this genus was thought to be monotypic (with ''Aztekium ritteri'') until a second species ('' Aztekium hintonii'') was discovered by George S. Hinton, in Galeana, Nuevo León in 1991. A further possible species, ''Aztekium valdezii'', was described in 2011, but is considered to be a synonym of ''A. ritteri''. Description ''Aztekium ritteri'' is a small plant (around 20 mm wide), with 9 to 11 ribs, which typically have transverse wrinkles. Its color varies from pale green to grayish-green. The center of the cactus contains a lot of white wool. Flowers are small (less than 10 mm wide), with white petals and pinkish sepals. The plants bear small pinkish berry-like fruits. ''A. hintonii'' is larger, to 10 cm in diameter, 10 to 18 grooved ribs, flowers magenta to 3 cm. It grows only on gypsum. Species Etymology Its name ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

N-Methyltyramine
''N''-Methyltyramine (NMT), also known as 4-hydroxy-''N''-methylphenethylamine, is a human trace amine and natural phenethylamine alkaloid found in a variety of plants.T. A. Smith (1977). "Phenethylamine and related compounds in plants." ''Phytochemistry'' 16 9 – 18. As the name implies, it is the N-methyl analog of tyramine, which is a well-known biogenic trace amine with which NMT shares many pharmacological properties. Biosynthetically, NMT is produced by the N-methylation of tyramine via the action of the enzyme phenylethanolamine ''N''-methyltransferase in humans and tyramine ''N''-methyltransferase in plants. Occurrence N-methyltyramine seems to be quite widely distributed in plants. NMT was isolated as a natural product for the first time, from germinating barley roots, by Kirkwood and Marion in 1950. These chemists found that 600 g of barley, after germination and 10-day growth, yielded 168 mg of N-methyltyramine.S. Kirkwood and L. Marion (1950) ''J. Am. Chem. S ...

Hordenine
Hordenine is an alkaloid of the phenethylamine class that occurs naturally in a variety of plants, taking its name from one of the most common, barley (''Hordeum'' species). Chemically, hordenine is the ''N''-methyl derivative of ''N''-methyltyramine, and the ''N'',''N''-dimethyl derivative of the well-known biogenic amine tyramine, from which it is biosynthetically derived and with which it shares some pharmacological properties (see below). , hordenine is widely sold as an ingredient of nutritional supplements, with the claims that it is a stimulant of the central nervous system, and has the ability to promote weight loss by enhancing metabolism. In experimental animals, given sufficiently large doses parenterally (by injection), hordenine does produce an increase in blood pressure, as well as other disturbances of the cardiovascular, respiratory, and nervous systems. These effects are generally not reproduced by oral administration of the drug in test animals, and virtually no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anhalidine
Anhalidine is a naturally occurring tetrahydroisoquinoline based alkaloid which can be isolated from ''Lophophora williamsii The peyote (; ''Lophophora williamsii'' ) is a small, spineless cactus which contains psychoactive alkaloids, particularly mescaline. ''Peyote'' is a Spanish word derived from the Nahuatl (), meaning "caterpillar cocoon", from a root , "to ...''; it has also been detected other cactii and several species of '' Acacia''. It is part of a family of compounds that are structurally related to mescaline. See also * Pellotine References Lophophora Isoquinoline alkaloids Norsalsolinol ethers {{alkaloid-stub ...

Mescaline
Mescaline or mescalin (3,4,5-trimethoxyphenethylamine) is a naturally occurring psychedelic protoalkaloid of the substituted phenethylamine class, known for its hallucinogenic effects comparable to those of LSD and psilocybin. Biological sources It occurs naturally in several species of cacti. It is also found in small amounts in certain members of the bean family, Fabaceae, including '' Acacia berlandieri''. However those claims concerning ''Acacia'' species have been challenged and have been unsupported in any additional analysis. History and use Peyote has been used for at least 5,700 years by Indigenous peoples of the Americas in Mexico. Europeans noted use of peyote in Native American religious ceremonies upon early contact, notably by the Huichols in Mexico. Other mescaline-containing cacti such as the San Pedro have a long history of use in South America, from Peru to Ecuador. While religious and ceremonial peyote use was widespread in the Aztec empire and nor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pellotine
Pellotine is an alkaloid found in ''Lophophora'' species. Pellotine is slightly narcotic, and has been used by Native Americans as a constituent of peyote for sacramental purposes. Psychological and physiological effects 8-10 mg of isolated pellotine is known to cause convulsions in frogs. When injected subcutaneously to humans, participants have reported drowsiness and a desire not to exert any physical or mental effort with one study reporting it to have hypnotic effects. It is also reported to lower blood pressure and heart rate. Ancient use Native inhabitants of north-eastern Mexico around 810–1070 CE (according to carbon dating) are thought to have used a number of "mescal beans" containing pellotine, among other alkaloids and mescaline. While it is known that these pellotine-containing beans were ornamental, it is unclear whether they were used for their psychoactive effects.

3-methoxytyramine
3-Methoxytyramine (3-MT), also known as 3-methoxy-4-hydroxyphenethylamine, is a human trace amine that occurs as a metabolite of the neurotransmitter dopamine. It is formed by the introduction of a methyl group to dopamine by the enzyme catechol-O-methyl transferase (COMT). 3-MT can be further metabolized by the enzyme monoamine oxidase (MAO) to form homovanillic acid (HVA), which is then typically excreted in the urine. Originally thought to be physiologically inactive, 3-MT has recently been shown to act as an agonist of human TAAR1. Occurrence 3-Methoxytyramine occurs naturally in the prickly pear cactus (genus ''Opuntia''), and is in general widespread throughout the Cactaceae. It has also been found in crown gall tumors on ''Nicotiana'' sp. In humans, 3-methoxytyramine is a trace amine that occurs as a metabolite of dopamine.

Cactoideae
The Cactoideae are the largest subfamily of the cactus family, Cactaceae. Around 80% of cactus species belong to this subfamily. , the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010. Various revisions have been published since, e.g. to the tribe Hylocereeae and the tribe Echinocereeae. Classifications remained uncertain . Tribes and genera , the National Center for Biotechnology Information used the division of the subfamily into tribes shown below. Some revisions to the circumscriptions of the tribes are also shown. * Blossfeldieae **''Blossfeldia'' *Browningieae **''Armatocereus'' – ''Browningia'' – ''Neoraimondia'' – '' Stetsonia'' *Cacteae **''Acharagma'' – ''Ariocarpus'' – ''Astrophytum'' – ''Aztekium'' – ''Coryphantha'' – '' Cumarinia'' – ''Echin ...
