Peperina
''Minthostachys verticillata'' is a species of flowering plant in the family ''Lamiaceae''. It is commonly known as peperina, is the only species of the genus '' Minthostachys'' known from Argentina. It occurs in the northwestern and central regions of the country. It may be the most economically important species of its genus, as it is collected extensively for its essential oil An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the ...s. These have been repeatedly examined for their composition, variability, and possible pharmacological effects.Zyglado, J.A., Maestri, D.M., Lamarque, A.L., Guzmán, C.A., Velasco-Negueruela, A., Pérez-Alonso, M.J., García-Vallejos, M.C., Grosso, N.R., 1996.

Minthostachys
''Minthostachys'' is a genus of the mint family Lamiaceae, comprising aromatic scandent shrubs. It occurs along the Andes from Northern Venezuela through Colombia, Ecuador, Peru and Bolivia to Central Argentina. Use and conservation The plants are valued by the local population for their content in essential oils, mostly pulegone and menthone, but also limonene, carvone, carvacrol, thymol and similar substances. They are used as condiments, medicinally against illnesses of the respiratory and digestive systems, and traditionally for the protection of stored tubers against pests, especially in Southern Peru. In Argentina and Peru, the essential oils are extracted commercially on a larger scale, and at least locally, this has led to overexploitation Overexploitation, also called overharvesting or ecological overshoot, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
August Grisebach
August Heinrich Rudolf Grisebach (; 17 April 18149 May 1879) was a German botanist and phytogeographer. Biography Grisebach studied at the Lyceum in Hanover, the cloister-school at Ilfeld, and the University of Göttingen. He graduated in medicine from the University of Berlin in 1836. He undertook expeditions to Provence, Turkey, the Balkans, and Norway. In 1837 he became associate professor and in 1847 full professor at the medical faculty in Göttingen and was named director of the botanical garden there in 1875. While his main fields of interest were phytogeography and systematics, especially the Gentianaceae and Malpighiaceae, he considered his ''Flora of the British West Indian Islands'' his most important work. Much of his collection, especially the types of species described by him, are housed at the Göttingen University Herbarium. His taxonomic classification is set out in his ''Grundriss der systematischen Botanik'' (1854). His son Eduard was an author, lawyer a ...

Carl Epling
Carl Clawson Epling (15 April 1894 – 17 November 1968) was an American botanist and taxonomist. Epling is best known for being the major authority on the Lamiaceae (mint family) of the Americas from the 1920s to the 1960s. In his later years he also developed an interest in genetics.

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamiaceae
The Lamiaceae ( ) or Labiatae are a family (biology), family of flowering plants commonly known as the mint, deadnettle, or sage family. Many of the plants are aromatic in all parts and include widely used culinary herbs like basil (herb), basil, mentha, mint, rosemary, Salvia officinalis, sage, savory (herb), savory, marjoram, oregano, Hyssopus officinalis, hyssop, thyme, lavender, and perilla, as well as traditional medicines such as catnip, ''Salvia'', Monarda, bee balm, Leonotis leonurus, wild dagga, and Leonurus japonicus, oriental motherwort. Some species are shrubs, trees (such as teak), or, rarely, vines. Many members of the family are widely cultivated, not only for their aromatic qualities, but also their ease of cultivation, since they are readily propagated by stem cuttings. Besides those grown for their edible leaves, some are grown for decorative foliage. Others are grown for seed, such as ''Salvia hispanica'' (chia), or for their edible tubers, such as ''Plectr ...

Argentina
Argentina, officially the Argentine Republic, is a country in the southern half of South America. It covers an area of , making it the List of South American countries by area, second-largest country in South America after Brazil, the fourth-largest country in the Americas, and the List of countries and dependencies by area, eighth-largest country in the world.

Essential Oil
An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is essential in the sense that it contains the essence of the plant's fragrance—the characteristic fragrance of the plant from which it is derived. The term "essential" used here does ''not'' mean required or usable by the human body, as with the terms essential amino acid or essential fatty acid, which are so called because they are nutritionally required by a living organism. Essential oils are generally extracted by distillation, often by using steam. Other processes include expression, solvent extraction, '' sfumatura'', absolute oil extraction, resin tapping, wax embedding, and cold pressing. They are used in perfumes, cosmetics, soaps, ...

Minthostachys Mollis
''Minthostachys mollis'' is a medicinal plant restricted to the South American Andes from Peru to Bolivia. It is the most variable and widely distributed species of the genus ''Minthostachys''. Its common name ''muña'' comes from Quechua. Other local names include ''tipo'', ''tipollo'', ''poleo''. Medicinal uses In the indigenous medicine traditions of the Andes, the plant is made into tea and used medicinally as a carminative and aphrodisiac. Chemical characteristics The principal components of essential oil are as follows: *pulegone *menthone *menthol *(−)- β-pinene *(−)- α-pinene *limonene * isomenthone * piperic acid *eucalyptol *carvone In the flowering tops 19 compounds were identified in the essential oil, predominantly 29% neomenthol, 24% menthone, 20% menthol, and 8% 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Argentina
The environment of Argentina is highly biodiverse. Biodiversity Flora Subtropical plants dominate the Gran Chaco in the north, with the '' Dalbergia'' genus of trees well represented by Brazilian rosewood and the quebracho tree; also predominant are the wacho white and black algarrobo trees ('' Prosopis alba'' and ''Prosopis nigra''). Savannah-like areas exist in the drier regions nearer the Andes. Aquatic plants thrive in the wetlands of Argentina. In central Argentina the ''humid pampas'' are a true tallgrass prairie ecosystem. In Argentina forest cover is around 10% of the total land area, equivalent to 28,573,000 hectares (ha) of forest in 2020, down from 35,204,000 ha in 1990. In 2020, naturally regenerating forest covered 27,137,000 ha and planted forest covered 1,436,000 ha. Of the naturally regenerating forest 0% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 7% o ...
