Oregano
Oregano (, ; ''Origanum vulgare'') is a species of flowering plant in the mint family, Lamiaceae. It was native to the Mediterranean region, but widely naturalised elsewhere in the temperate climate, temperate Northern Hemisphere. Oregano is a woody perennial plant, growing to tall, with opposite leaves long. The flowers which can be white, pink or light purple, are long, and produced in erect spikes in summer. It is sometimes called wild marjoram, while its close relative ''Origanum majorana, O. majorana'' is known as sweet marjoram. Both are widely used as Herb, culinary herbs, especially in Turkish, Greek, Spanish, Italian, Latin, and French cuisine. Oregano is also an ornamental plant, with numerous cultivars bred for varying leaf colour, flower colour and habit. Etymology The English word "oregano" is a borrowing of the Spanish language, Spanish , which derives from the Latin , which itself comes from Classical Greek (''orī́ganon''). The ultimate origin is dispu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marjoram
Marjoram (, ''Origanum majorana'') is a cold-sensitive perennial plant, perennial herb or undershrub with sweet pine and citrus flavours. In some Middle Eastern countries, marjoram is synonymous with oregano, and there the names sweet marjoram and knotted marjoram are used to distinguish it from other plants of the genus ''Origanum''. It is also called pot marjoram, although this name is also used for other cultivated species of ''Origanum''. History Marjoram is indigenous to Cyprus, the Mediterranean, Turkey, Western Asia, the Arabian Peninsula, and the Levant, and was known to the ancient Ancient Greece, Greeks and Ancient Rome, Romans as a symbol of happiness. It may have spread to the British Isles during the Middle Ages. Marjoram was not widely used in the United States until after World War II. The name marjoram (Old French: ''majorane''; ) does not directly derive from the Latin word (major). Marjoram is related to Samhain, the Ancient Celtic religion, Celtic pagan ho ...

Origanum Vulgare Inflorescence - Keila
''Origanum'' ( ) is a genus of herbaceous perennial flowering plants and subshrubs in the family Lamiaceae. They are native to Europe, North Africa, and much of temperate Asia, where they are found in open or mountainous habitats. A few species also naturalized in scattered locations in North America and other regions. The plants have strongly aromatic leaves and abundant tubular flowers with long-lasting coloured bracts. The genus includes the important group of culinary herbs: marjoram (''Origanum majorana'') and oregano (''Origanum vulgare''). With their decorative bracts, ''Origanum'' species and cultivars are used as ornamental plants in the garden. The cultivars 'Kent Beauty' and 'Rosenkuppel' have received the Royal Horticultural Society's Award of Garden Merit. ''Origanum'' species are used as food plants by the larvae of some Lepidoptera species, including ''Coleophora albitarsella''. Species # ''Origanum acutidens'' (Hand.-Mazz.)

Thymol
Thymol (also known as 2-isopropyl-5-methylphenol, IPMP), , is a toxic monoterpenoid phenol derivative of ''p''-Cymene, isomeric with carvacrol. It occurs naturally in the oil of thyme, and it is extracted from ''Thymus vulgaris'' (common thyme), ajwain, and various other plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties. Thymol also provides the distinctive, strong flavor of the culinary herb thyme, also produced from ''T. vulgaris''. Thymol is only slightly soluble in water at neutral pH, but it is extremely soluble in alcohols and other organic solvents. It is also soluble in strongly alkaline aqueous solutions due to deprotonation of the phenol. Its dissociation constant ( p''K''a) is . Thymol absorbs maximum UV radiation at 274 nm. Chemical synthesis Thymol is produced by the alkylation of ''m''-cresol and propene: : A predicted method of biosynthesis of thymol in thyme and oregano begins with the cyclizati ...

Carvacrol
Carvacrol, or cymophenol, C6H3(CH3)(OH)C3H7, is a monoterpene, monoterpenoid phenol. It has a characteristic pungent, warm odor of oregano. Natural occurrence Carvacrol is present in the essential oil of ''Origanum vulgare'' (oregano), oil of thyme, oil obtained from Lepidium, pepperwort, and Monarda fistulosa, wild bergamot. The essential oil of thyme subspecies contains between 5% and 75% of carvacrol, while ''Satureja'' (savory) subspecies have a content between 1% and 45%. ''Origanum majorana'' (marjoram) and Dittany of Crete are rich in carvacrol, 50% and 60–80% respectively. It is also found in tequila and ''Lippia graveolens'' (Mexican oregano) in the verbena family.

Herb
Herbs are a widely distributed and widespread group of plants, excluding vegetables, with savory or aromatic properties that are used for flavoring and garnishing food, for medicinal purposes, or for fragrances. Culinary use typically distinguishes herbs from spices. ''Herbs'' generally refers to the leafy green or flowering parts of a plant (either fresh or dried), while ''spices'' are usually dried and produced from other parts of the plant, including seeds, bark, roots and fruits. Herbs have a variety of uses including culinary, medicinal, aromatic and in some cases, spiritual. General usage of the term "herb" differs between culinary herbs and medicinal herbs; in medicinal or spiritual use, any parts of the plant might be considered "herbs", including leaves, roots, flowers, seeds, root bark, inner bark (and cambium), resin and pericarp. The word "herb" is pronounced in Commonwealth English, but is standard among American English speakers as well as those from regio ...

Monoterpenoid
Monoterpenes are a class of terpenes that consist of two isoprene units and have the molecular formula C10H16. Monoterpenes may be linear (acyclic) or contain rings (monocyclic and bicyclic). Modified terpenes, such as those containing oxygen functionality or missing a methyl group, are called monoterpenoids. Monoterpenes and monoterpenoids are diverse. They have relevance to the pharmaceutical, cosmetic, agricultural, and food industries. Biosynthesis Monoterpenes are derived biosynthetically from units of isopentenyl pyrophosphate, which is formed from acetyl-CoA via the intermediacy of mevalonic acid in the HMG-CoA reductase pathway. An alternative, unrelated biosynthesis pathway of IPP is known in some bacterial groups and the plastids of plants, the so-called MEP-(2-methyl-D-erythritol-4-phosphate) pathway, which is initiated from C5 sugars. In both pathways, IPP is isomerized to DMAPP by the enzyme isopentenyl pyrophosphate isomerase. Geranyl pyrophosphate is the precursor ...

Mint Family
The Lamiaceae ( ) or Labiatae are a 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, mint, rosemary, sage, savory, marjoram, oregano, hyssop, thyme, lavender, and perilla, as well as traditional medicines such as catnip, ''Salvia'', bee balm, wild dagga, and 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 ''Plectranthus edulis'', '' P. esculentus'', '' P. rotundifolius'', and '' Stachys affinis'' (Chinese artichoke). Many are also grown orn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flavones
Flavones (from Latin ''flavus'' "yellow") are a class of flavonoids based on the backbone of 2-phenylchromen-4-one (2-phenyl-1-benzopyran-4-one) (as shown in the first image of this article). Flavones are common in foods, mainly from spices, and some yellow or orange fruits and vegetables. Common flavones include apigenin (4',5,7-trihydroxyflavone), luteolin (3',4',5,7-tetrahydroxyflavone), tangeritin (4',5,6,7,8-pentamethoxyflavone), chrysin (5,7-dihydroxyflavone), and 6-hydroxyflavone. Intake and elimination The estimated daily intake of flavones is about 2 mg per day. Following ingestion and metabolism, flavones, other polyphenols, and their metabolites are absorbed poorly in body organs and are rapidly excreted in the urine, indicating mechanisms influencing their presumed absence of metabolic roles in the body. Drug interactions Flavones have effects on CYP (P450) activity, which are enzymes that metabolize most drugs in the body. Biosynthesis The biosynthesis of ...
