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 (chemistry), derivative of N-Methyltyramine, ''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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Candicine
Candicine is a naturally occurring organic compound that is a quaternary ammonium salt with a phenethylamine skeleton. It is the N,N,N-trimethyl derivative of the well-known biogenic amine tyramine, and, being a natural product with a positively charged nitrogen atom in its molecular structure, it is classed as an alkaloid. Although it is found in a variety of plants, including barley, its properties have not been extensively studied with modern techniques. Candicine is toxic after parenteral administration, producing symptoms of neuromuscular blocking drug, neuromuscular blockade; further details are given in the "Pharmacology" section below. Occurrence Candicine occurs in a variety of plants, notably the cacti. This alkaloid was first isolated from the Argentinian cactus ''Trichocereus candicans'' (now reclassified as ''Echinopsis candicans''), from which it derives its name, and from other ''Trichocereus'' species. ''T. candicans'' may contain up to 5% candicine, and is also a r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tyramine
Tyramine ( ) (also spelled tyramin), also known under several other names, is a naturally occurring trace amine derived from the amino acid tyrosine. Tyramine acts as a catecholamine releasing agent. Notably, it is unable to cross the blood-brain barrier, resulting in only non-psychoactive peripheral sympathomimetic effects following ingestion. A hypertensive crisis can result, however, from ingestion of tyramine-rich foods in conjunction with the use of monoamine oxidase inhibitors (MAOIs). Occurrence Tyramine occurs widely in plants and animals, and is metabolized by various enzymes, including monoamine oxidases. In foods, it often is produced by the decarboxylation of tyrosine during fermentation or decay. Foods that are fermented, cured, pickled, aged, or spoiled have high amounts of tyramine. Tyramine levels go up when foods are at room temperature or go past their freshness date. Specific foods containing considerable amounts of tyramine include: * strong or ag ...

N-Methyltyramine
''N''-Methyltyramine (NMT), also known as 4-hydroxy-''N''-methylphenethylamine, is a human trace amine and natural substituted phenethylamine, 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 amine, 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, phenylethanolamine ''N''-methyltransferase in humans and tyramine N-methyltransferase, 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 germinat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hordeum Vulgare
Barley (''Hordeum vulgare''), a member of the grass family, is a major cereal grain grown in temperate climates globally. It was one of the first cultivated grains, particularly in Eurasia as early as 10,000 years ago. Globally 70% of barley production is used as animal fodder, while 30% as a source of fermentable material for beer and certain distilled beverages, and as a component of various foods. It is used in soups and stews, and in barley bread of various cultures. Barley grains are commonly made into malt in a traditional and ancient method of preparation. In 2017, barley was ranked fourth among grains in quantity produced () behind maize, rice and wheat. Etymology The Old English word for barley was ', which traces back to Proto-Indo-European and is cognate to the Latin word ' "flour" (''see corresponding entries''). The direct ancestor of modern English ''barley'' in Old English was the derived adjective ''bærlic'', meaning "of barley". The first citation of th ...

Ariocarpus Fissuratus
''Ariocarpus fissuratus'' (formerly known as ''Anhalonium fissuratus'') is a species of cactus found in small numbers in northern Mexico and Texas in the United States. Common names include living rock cactus, false peyote, chautle, dry whiskey and star cactus. Description This cactus consists of many small tubercles growing from a large tap root. They are usually solitary, rarely giving rise to side shoots from old areoles. The plant is greyish-green in color, sometimes taking on a yellowish tint with age. Its growth rate is extremely slow. ''A. fissuratus'' is naturally camouflaged in its habitat, making it difficult to spot. When they are found, it is usually due to their pinkish flowers which bloom in October and early November. Cultivation In cultivation, ''Ariocarpus fissuratus'' is often grafted to a faster-growing columnar cactus to speed growth, as they would generally take at least a decade to reach maturity on their own. They require very little water and fertilize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sorghum
''Sorghum'' () is a genus of about 25 species of flowering plants in the grass family (Poaceae). Some of these species are grown as cereals for human consumption and some in pastures for animals. One species is grown for grain, while many others are used as fodder plants, either cultivated in warm climates worldwide or naturalized in pasture lands. Taxonomy ''Sorghum'' is in the Poaceae (grass) subfamily Panicoideae and the tribe Andropogoneae (the same as maize, big bluestem and sugarcane). Species Accepted species recorded include: Distribution and habitat Seventeen of the 25 species are native to Australia, with the range of some extending to Africa, Asia, Mesoamerica, and certain islands in the Indian and Pacific Oceans. Toxicity In the early stages of the plants' growth, some species of sorghum can contain levels of hydrogen cyanide, hordenine, and nitrates, which are lethal to grazing animals. Plants stressed by drought or heat can also contain toxic lev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Methyl Hordenine HCl
In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula . In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds. It is a very stable group in most molecules. While the methyl group is usually part of a larger molecule, bounded to the rest of the molecule by a single covalent bond (), it can be found on its own in any of three forms: methanide anion (), methylium cation () or methyl radical (). The anion has eight valence electrons, the radical seven and the cation six. All three forms are highly reactive and rarely observed. Methyl cation, anion, and radical Methyl cation The methylium cation () exists in the gas phase, but is otherwise not encountered. Some compounds are considered to be sources of the cation, and this simplification is used pervasively in organic chemistry. For example, protonation of methanol gives an electr ...
