Tomitaro Makino
image:Makino Tomitaro.jpg, 200px, Tomitaro Makino was a pioneer Japanese botanist noted for his taxonomic work. He has been called "Father of Japanese Botany". He was one of the first Japanese botanists to work extensively on classifying Japanese plants using the system developed by Carl Linnaeus, Linnaeus. His research resulted in documenting 50,000 specimens, many of which are represented in his ''Makino's Illustrated Flora of Japan''. Despite having dropped out of grammar school, he eventually attained a Doctor of Science degree, and his birthday is remembered as ''Botany Day'' in Japan. Early life Tomitaro Makino was born in Sakawa, Kōchi, Sakawa, Kōchi Prefecture, Kōchi to a prestigious sake brewer. His parents died during his early childhood, and he was raised mainly by his grandmother. Though he dropped out of school after two years, he cultivated a strong interest in English, geography, and especially in botany. In 1880, he became a teacher at the Primary education ...

Chromosome
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated ( S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mentha Pulegium
''Mentha pulegium'', commonly (European) pennyroyal, or pennyrile, also called mosquito plant and pudding grass, is a species of flowering plant in the mint family, Lamiaceae, native to Europe, North Africa, and the Middle East. Crushed pennyroyal leaves emit a very strong fragrance similar to spearmint. Pennyroyal is a traditional folk remedy, emmenagogue, abortifacient, and culinary herb, but is toxic to the liver and has caused some deaths. European pennyroyal is related to an American species, Hedeoma pulegioides. Though they differ in genera, they share similar chemical properties. Description An annual to perennial plant with creeping or erect branched stems to about 40 cm in height. The stems are square in cross-section and can vary from hairless on some plants to densely hairy on others, with a green to sometimes red or purplish colour. The leaves, which grow in opposite pairs, are narrowly oval, 2–3 cm long x 1 cm wide, downy, sparsely toothed towar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linalool
Linalool () refers to two enantiomers of a naturally occurring terpene alcohol found in many flowers and spice plants. Linalool has multiple commercial applications, the majority of which are based on its pleasant scent (floral, with a touch of spiciness). A colorless oil, linalool is classified as an acyclic monoterpenoid. In plants, it is a metabolite, a volatile oil component, an antimicrobial agent, and an aroma compound. Linalool has uses in manufacturing of soaps, fragrances, food additives as flavors, household products, and insecticides. Esters of linalool are referred to as linalyl, e.g. linalyl pyrophosphate, an isomer of geranyl pyrophosphate. The word ''linalool'' is based on '' linaloe'' (a type of wood) and the suffix '. In food manufacturing, it may be called ''coriandrol''. Occurrence Both enantiomeric forms are found in nature: (''S'')-linalool is found, for example, as a major constituent of the essential oils of coriander (''Coriandrum sativum'' L.), cymbopo ...

Carvone
Carvone is a member of a family of chemicals called terpenoids. Carvone is found naturally in many essential oils, but is most abundant in the oils from seeds of caraway (''Carum carvi''), spearmint (''Mentha spicata''), and dill. Uses Both carvones are used in the food and flavor industry. ''R''-(−)-Carvone is also used for air freshening products and, like many essential oils, oils containing carvones are used in aromatherapy and alternative medicine. ''S''-(+)-Carvone has shown a suppressant effect against high-fat diet induced weight gain in mice. Food applications As the compound most responsible for the flavor of caraway, dill and spearmint, carvone has been used for millennia in food. Wrigley's Spearmint Gum and spearmint flavored Life Savers are major users of natural spearmint oil from ''Mentha spicata''. Caraway seed is extracted with alcohol to make the European drink Kümmel. Agriculture ''S''-(+)-Carvone is also used to prevent premature sprouting of potatoes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menthol
Menthol is an organic compound, more specifically a monoterpenoid, made synthetically or obtained from the oils of corn mint, peppermint, or other mints. It is a waxy, clear or white crystalline substance, which 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'') configuration. Menthol has local anesthetic and counterirritant qualities, and it is widely used to relieve minor throat irritation. Menthol also acts as a weak κ-opioid receptor agonist. Structure Natural menthol exists as one pure stereoisomer, nearly always the (1''R'',2''S'',5''R'') form (bottom left corner of the diagram below). The eight possible stereoisomers are: : In the natural compound, the isopropyl group is in the ''trans'' orientation to both the methyl and hydroxyl groups. Thus, it can be drawn in any of the ways shown: : The (+)- and (−)-enantiomers of menthol are the most stable among ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mentha Gattefossei
''Mentha gattefossei'' is a plant species in the genus ''Mentha'', endemic to the Atlas Mountains of Morocco. It was first described by French botanist René Maire in 1922. Harvested for its essential oil, ''M. gattefossei'' has seen use in traditional medicine, pest control and as a food seasoning. Name When he described it in 1922, Maire named ''Mentha gattefossei'' in honor of botanist Jean Gattefossé, in recognition of his contributions to the study of Moroccan herbs and aromatic plants. Its vernacular names include Arabic , as well as French and . Taxonomy ''Mentha gattefossei'' is accepted as a distinct species by authorities such as Plants of the World Online. Within the mints, it has historically been grouped with relatives such as ''Mentha pulegium'', ''Mentha requienii'' and ''Mentha grandiflora'' within the "Pulegium" section. This was owing to a homoplasy in morphological features between it and ''M. pulegium''. Maire himself, however, had speculated an ancestral ...
