Pudina
''Mentha arvensis'', the corn mint, field mint, or wild mint, is a species of flowering plant in the mint family Lamiaceae. It has a circumboreal distribution, being native to the temperate regions of Europe and western and central Asia, east to the Himalaya and eastern Siberia, and North America. '' Mentha canadensis'', the related species, is also included in ''Mentha arvensis'' by some authors as two varieties, ''M. arvensis'' var. ''glabrata'' Fernald (North American plants such as American Wild Mint) and ''M. arvensis'' var. ''piperascens'' Malinv. ex L. H. Bailey (eastern Asian plants such as Japanese mint). It grows in moist places, especially along streams. Description Wild mint is a herbaceous perennial plant generally growing to and rarely up to tall. It has a creeping rootstock from which grow erect or semi-sprawling squarish stems. The leaves are in opposite pairs, simple, long and broad, hairy, and with a coarsely serrated margin. The flowers are pale purple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mentha
''Mentha'', also known as mint (from Greek , Linear B ''mi-ta''), is a genus of flowering plants in the mint family, Lamiaceae. It is estimated that 13 to 24 species exist, but the exact distinction between species is unclear. Hybridization occurs naturally where some species' ranges overlap. Many hybrids and cultivars are known. The genus has a subcosmopolitan distribution, growing best in wet environments and moist soils. Description Mints are aromatic, almost exclusively perennial herbs. They have wide-spreading underground and overground stolons and erect, square, branched stems. Mints will grow tall and can spread over an indeterminate area. Due to their tendency to spread unchecked, some mints are considered invasive. The leaves are arranged in opposite pairs, from oblong to lanceolate, often downy, and with a serrated margin. Leaf colors range from dark green and gray-green to purple, blue, and sometimes pale yellow. The flowers are produced in long bracts ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, 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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Sole
William Sole (1739–7 February 1802) was a British people, British apothecary and botanist. The ''Oxford Dictionary of National Biography'' states that William Sole was born in 1741 in Little Thetford, Cambridgeshire,The current 2004 edition of the ''Oxford Dictionary of National Biography'' gives Thetford in Norfolk, but older editions and contemporary documents state that Sole was born in Cambridgeshire. However, evidence suggest that he was born in 1739 and Baptised on 28 September in Witchford, Cambridgeshire. William Sole was the first son of John and Martha Sole. Sometime after his birth, the family moved to Little Thetford. John and Martha had a further six children. John (baptised 14 June 1741), Sarah (baptised 15 May 1743), Elizabeth (baptised 24 February 1744), Francis (baptised 19 February 1748), Robert (baptised 13 May 1750), Martha (baptised 1752 3 October). In his will dated 15 March 1802, Sole mentions all of his siblings, with the exception of Elizabeth. Sole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caryophyllene
Caryophyllene (), more formally (−)-β-caryophyllene (BCP), is a natural bicyclic sesquiterpene that occurs widely in nature. Caryophyllene is notable for having a cyclobutane ring, as well as a ''trans''-double bond in a 9-membered ring, both rarities in nature. Production Caryophyllene can be produced synthetically, but it is invariably obtained from natural sources because it is widespread. It is a constituent of many essential oils, especially clove oil, the oil from the stems and flowers of ''Syzygium aromaticum'' (cloves), the essential oil of ''Cannabis sativa'', copaiba, rosemary, and hops. It is usually found as a mixture with isocaryophyllene (the ''cis'' double bond isomer) and humulene, α-humulene (obsolete name: α-caryophyllene), a ring-opened isomer. Caryophyllene is one of the chemical compounds that contributes to the odor, aroma of black pepper. Basic research β-Caryophyllene is under basic research for its potential action as an agonist of the cannab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piperitone
Piperitone is a natural monoterpene ketone which is a component of some essential oils. Both stereoisomers, the D-form and the L-form, are known. The D-form has a peppermint-like aroma and has been isolated from the oils of plants from the genera ''Cymbopogon'', ''Andropogon'', and ''Mentha''. The L-form has been isolated from Sitka spruce. Occurrence Piperitone is found in many essential oils, including over thirty species of the genus ''Eucalyptus''. High levels are present in certain species of ''Eucalyptus'' and ''Mentha''. In the genus Eucalyptus, the highest concentrations are found in ''Eucalyptus dives''. Both enantiomers occur naturally. In Eucalyptus species, (-)-piperitone is present; in mint species, (+)-piperitone is found; and some plants contain racemate piperitone. Properties Piperitone is a colorless liquid with a distinct peppermint odor. Production Piperitone can be synthesized from isopropyl acetoacetate and 3-buten-2-one. The primary source of D ...

Methyl Acetate
Methyl acetate, also known as MeOAc, acetic acid methyl ester or methyl ethanoate, is a carboxylate ester with the formula CH3COOCH3. It is a flammable liquid with a characteristically pleasant smell reminiscent of some glues and nail polish removers. Methyl acetate is occasionally used as a solvent, being weakly polar and lipophilic, but its close relative ethyl acetate is a more common solvent being less toxic and less soluble in water. Methyl acetate has a solubility of 25% in water at room temperature. At elevated temperature its solubility in water is much higher. Methyl acetate is not stable in the presence of strong aqueous bases or aqueous acids. Methyl acetate is not regulated as a volatile organic compound in the USA. Preparation and reactions Methyl acetate is produced industrially via the carbonylation of methanol as a byproduct of the production of acetic acid. Methyl acetate also arises by esterification of acetic acid with methanol in the presence of strong a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limonene
Limonene () is a colorless liquid aliphatic hydrocarbon classified as a cyclic monoterpene, and is the major component in the essential oil of citrus fruit peels. The (+)-isomer, occurring more commonly in nature as the fragrance of oranges, is a flavoring agent in food manufacturing. It is also used in chemical synthesis as a precursor to carvone and as a renewables-based solvent in cleaning products. The less common (−)-isomer has a piny, turpentine-like odor, and is found in the edible parts of such plants as caraway, dill, and bergamot orange plants. Limonene takes its name from Italian ''limone'' ("lemon"). Limonene is a chiral molecule, and biological sources produce one enantiomer: the principal industrial source, citrus fruit, contains (+)-limonene (''d''-limonene), which is the (''R'')-enantiomer. (+)-Limonene is obtained commercially from citrus fruits through two primary methods: centrifugal separation or steam distillation. In plants (+)-Limonene ...

Neomenthol
Menthol is an organic compound, specifically a Monoterpene, monoterpenoid, that occurs naturally in the oils of several plants in the Mentha, mint family, such as Mentha arvensis, corn mint and peppermint. It is a white or clear waxy crystalline substance that is solid at room temperature and melts slightly above. The main form of menthol occurring in nature is (−)-menthol, which is assigned the (1''R'',2''S'',5''R'') Cahn–Ingold–Prelog priority rules, configuration. For many people, menthol produces a cooling sensation when inhaled, eaten, or applied to the skin, and mint plants have been used for centuries for topical pain relief and as a food flavoring. Menthol has local anesthetic and counterirritant qualities, and it is widely used to relieve minor throat irritation. Menthol has been demonstrated to cause a subjective nasal decongestant effect without any objective decongestant action, and administration of menthol via a nasal inhaler in humans has also been shown t ...

Menthone
Menthone is a chemical compound of the monoterpene class of naturally occurring organic compounds found in a number of essential oils, one that presents with minty flavor. It is a specific pair of stereoisomers of the four possible such isomers for the chemical structure, 2-isopropyl-5-methylcyclohexanone. Of those, the stereoisoomer ''l''-menthone—formally, the (2''S'',5''R'')-''trans'' isomer of that structure, as shown at right—is the most abundant in nature. Menthone is structurally related to menthol, which has a secondary alcohol (>C-OH) in place of the carbon-oxygen double bond (carbonyl group) projecting from the cyclohexane ring. Menthone is obtained for commercial use after purifying essential oils pressed from Mentha species (peppermint and corn mint). It is used as a flavorant and in perfumes and cosmetics for its characteristic aromatic and minty aroma. Occurrence Menthone is a constituent of the essential oils of pennyroyal, peppermint, '' corn mint'', '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
