Cedrol
Cedrol is a sesquiterpene alcohol found in the essential oil of conifers (cedar oil), especially in the genera '' Cupressus'' (cypress) and ''Juniperus'' (juniper). It has also been identified in '' Origanum onites'', a plant related to oregano. Its main uses are in the chemistry of aroma compounds. It makes up about 19% of cedarwood oil Texas and 15.8% of cedarwood oil Virginia. Cedrol has not been proven to be toxic in humans. It has been shown to have antioxidant and antiinflammatory along with other beneficial effects. In skin sensitization tests 2/20 people showed negative effects, and on the second test there was no sensitivity found. This compound and ones similar have been found to have antiseptic, anti-inflammatory, antispasmodic, tonic, astringent, diuretic, sedative, insecticidal, and antifungal activities ''in vitro''. These compounds are used globally in traditional medicine and cosmetics. Results of a 2015 study suggest that cedrol strongly attracts pregnant femal ...

Cedar Oil
Cedar oil, also known as cedarwood oil, is an essential oil derived from various types of conifers, most in the pine or cypress botanical families. It is produced from the foliage, and sometimes the wood, roots, and stumps left after logging of trees for timber. It has many uses in art, industry, and perfumery, and while the characteristics of oils derived from various species may vary, all have some degree of pesticidal effects. Sources and characteristics Although termed cedar or cedarwood oils, the most important oils are produced from distilling wood of a number of different junipers and cypresses (of the family Cupressaceae), rather than true cedars (of the family Pinaceae). Similar oils are distilled, pressed or chemically extracted in small quantities from wood, roots, and leaves from plants of the genera '' Platycladus'', ''Cupressus'', ''Taiwania'', and ''Calocedrus''. The cedarwood oil of the ancients, in particular the Sumerians and Egyptians, was derived from the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Origanum Onites
''Origanum onites'', the Cretan oregano, Greek oregano, pot marjoram or Ellinikí rίgani in Greek (Ελληνική ρίγανη), is a plant species in the genus ''Origanum'' found in Sicily, Greece and Turkey. It has similar flavors as oregano. Its essential oil can be distinguished from other species such as Greek oregano ('' Origanum vulgare ssp. hirtum''). It has antimicrobial activities.

Sesquiterpene
Sesquiterpenes are a class of terpenes that consist of three isoprene units and often have the molecular formula C15H24. Like monoterpenes, sesquiterpenes may be cyclic or contain rings, including many unique combinations. Biochemical modifications such as oxidation or rearrangement produce the related sesquiterpenoids. Sesquiterpenes are found naturally in plants and insects, as semiochemicals, e.g. defensive agents or pheromones. Biosynthesis and examples The reaction of geranyl pyrophosphate with isopentenyl pyrophosphate results in the 15-carbon farnesyl pyrophosphate (FPP), which is an intermediate in the biosynthesis of sesquiterpenes such as farnesene. Cyclic sesquiterpenes are more common than cyclic monoterpenes because of the increased chain length and additional double bond in the sesquiterpene precursors. In addition to common six-membered ring systems such as the ones found in zingiberene and bisacurone, cyclization of one end of the chain to the other end can ...

Alcohol (chemistry)
In chemistry, an alcohol is a type of organic compound that carries at least one hydroxyl () functional group bound to a saturated carbon atom. The term ''alcohol'' originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. An important class of alcohols, of which methanol and ethanol are the simplest examples, includes all compounds which conform to the general formula . Simple monoalcohols that are the subject of this article include primary (), secondary () and tertiary () alcohols. The suffix ''-ol'' appears in the IUPAC chemical name of all substances where the hydroxyl group is the functional group with the highest priority. When a higher priority group is present in the compound, the prefix ''hydroxy-'' is used in its IUPAC name. The suffix ''-ol'' in non-IUPAC names (such as paracetamol or cholesterol) also typically indicates that the substance is an alcohol. However, some comp ...

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 indispensable 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, soap ...

Conifer
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime ada ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cupressus
''Cupressus'' is one of several genera of evergreen conifers within the family Cupressaceae that have the common name cypress; for the others, see cypress. It is considered a polyphyletic group. Based on genetic and morphological analysis, the genus ''Cupressus'' is found in the subfamily Cupressoideae. The common name "cypress" comes via the Old French ''cipres'' from the Latin ''cyparissus'', which is the latinisation of the Greek κυπάρισσος (''kypárissos''). Taxonomy There has long been significant uncertainty about the New World members of ''Cupressus'', with several studies recovering them as forming a distinct clade from the Old World members. A 2021 molecular study found ''Cupressus'' to be the sister genus to '' Juniperus'', whereas the western members (classified in '' Callitropsis'' and '' Hesperocyparis'') were found to be sister to '' Xanthocyparis''. Description They are evergreen trees or large shrubs, growing to 5–40 m tall. The leaves are sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juniperus
Junipers are coniferous trees and shrubs in the genus ''Juniperus'' () of the cypress family Cupressaceae. Depending on the taxonomy, between 50 and 67 species of junipers are widely distributed throughout the Northern Hemisphere, from the Arctic, south to tropical Africa, throughout parts of western, central and southern Asia, east to eastern Tibet in the Old World, and in the mountains of Central America. The highest-known juniper forest occurs at an altitude of in southeastern Tibet and the northern Himalayas, creating one of the highest tree lines on earth. Description Junipers vary in size and shape from tall trees, tall, to columnar or low-spreading shrubs with long, trailing branches. They are evergreen with needle-like and/or scale-like leaves. They can be either monoecious or dioecious. The female seed cones are very distinctive, with fleshy, fruit-like coalescing scales which fuse together to form a berrylike structure ( galbulus), long, with one to 12 unw ...

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 Northern Hemisphere. Oregano is a woody perennial plant, growing tall, with opposite leaves long. The flowers are purple, long, produced in erect spikes in summer. It is sometimes called wild marjoram, and its close relative, '' O. majorana'', is known as sweet marjoram. Both are widely used as culinary herbs, especially in Turkish, Greek, Spanish, Italian, Mexican, and French cuisine. Oregano is also an ornamental plant, with numerous cultivars bred for varying leaf colour, flower colour and habit. Etymology Used since the middle 18th century, the Spanish word ''orégano'' is derived from the Latin ''orīganum'' and ultimately from the Classical Greek (''orī́ganon''). This is a compound Greek term that consists of (''óros'') meaning "mountain", and (''gános'') meaning "bright ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aroma Compounds
An aroma compound, also known as an odorant, aroma, fragrance or flavoring, is a chemical compound that has a smell or odor. For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently volatile for transmission via the air to the olfactory system in the upper part of the nose. As examples, various fragrant fruits have diverse aroma compounds, particularly strawberries which are commercially cultivated to have appealing aromas, and contain several hundred aroma compounds. Generally, molecules meeting this specification have molecular weights of less than 310. Flavors affect both the sense of taste and smell, whereas fragrances affect only smell. Flavors tend to be naturally occurring, and the term ''fragrances'' may also apply to synthetic compounds, such as those used in cosmetics. Aroma compounds can naturally be found in various foods, such as fruits and their peels, wine, spices, floral scent, perfumes, fragrance ...

In Vitro
''In vitro'' (meaning in glass, or ''in the glass'') studies are performed with microorganisms, cells, or biological molecules outside their normal biological context. Colloquially called " test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates. Studies conducted using components of an organism that have been isolated from their usual biological surroundings permit a more detailed or more convenient analysis than can be done with whole organisms; however, results obtained from ''in vitro'' experiments may not fully or accurately predict the effects on a whole organism. In contrast to ''in vitro'' experiments, '' in vivo'' studies are those conducted in living organisms, including humans, and whole plants.
