Nerolidol
Nerolidol, also known as peruviol and penetrol , is a naturally occurring sesquiterpene alcohol. A colorless liquid, it is found in the essential oils of many types of plants and flowers. There are four isomers of nerolidol', which differ in the geometry about the internal double bonds, but most applications use such a mixture. The aroma of nerolidol is woody and reminiscent of fresh bark. It is used as a flavoring agent and in perfumery as well as in non-cosmetic products such as detergents and cleansers. Nerolidyl derivatives involve include nerolidyl diphosphate and the fragrance nerolidyl acetate. Synthesis and occurrence Nerolidol is produced commercially from geranylacetone by the addition of vinyl Grignard reagent. It is used as a source of farnesol, vitamin E, and vitamin K1. Significant sources of natural nerolidol is Cabreuva oil and the oil of ''Dalbergia parviflora''. It is also present in neroli, ginger, jasmine, lavender, tea tree, ''Cannabis sativa'', and l ...

Bisabolol
Bisabolol, or more formally α-(−)-bisabolol or also known as levomenol, is a natural monocyclic sesquiterpene alcohol. It is a colorless viscous oil that is the primary constituent of the essential oil from German chamomile (''Matricaria recutita'') and ''Myoporum crassifolium''. High concentrations of bisabolol can also be found in certain medicinal cannabis cultivars. It is poorly soluble in water and glycerine, but soluble in ethanol. The enantiomer, α-(+)-bisabolol, is also found naturally but is rare. Synthetic bisabolol is usually a racemic mixture of the two, α-(±)-bisabolol. It is the terpenoid responsible for distinctive aroma of chamomile flowers, and when isolated, its scent has also has been likened to apples, sugar and honey. Bisabolol has a weak sweet floral aroma and is used in various fragrances. It has also been used for hundreds of years in cosmetics because of its skin healing properties including reducing wrinkles, skin toughness and repairing sun ...

The (−)-isomer was isolated in 1951 by Haagen-Smit and others from ''Pinus albicaulus'' and first called albicaulol. Its structure was determined in 1970 by Lars Westfelt. Other names were given to δ-cadinol based on its various biological sources before the structures were confirmed, including sesquigoyol for (+)-δ-cadinol and pilgerol for (−)-δ-cadinol.

The taste of cubebol is cooling and refreshing. The patent describes application of cubebol as a refreshing agent in various products, ranging from chewing gum to sorbets, drinks, toothpaste, and gelatin Gelatin or gelatine (from la, gelatus meaning "stiff" or "frozen") is a translucent, colorless, flavorless food ingredient, commonly derived from collagen taken from animal body parts.

Farnesol
Farnesol is a natural 15-carbon organic compound which is an acyclic sesquiterpene alcohol. Under standard conditions, it is a colorless liquid. It is hydrophobic, and thus insoluble in water, but miscible with oils. Farnesol is produced from 5-carbon isoprene compounds in both plants and animals. Phosphate-activated derivatives of farnesol are the building blocks of possibly all acyclic sesquiterpenoids. These compounds are doubled to form 30-carbon squalene, which is the precursor for steroids in plants, animals, and fungi. Farnesol and its derivatives are important starting compounds for natural and artificial organic synthesis. Uses Farnesol is present in many essential oils such as citronella, neroli, cyclamen, lemon grass, tuberose, rose, musk, balsam, and tolu. It is used in perfumery to emphasize the odors of sweet, floral perfumes. It enhances perfume scent by acting as a co-solvent that regulates the volatility of the odorants. It is especially used in lilac perf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carotol
Carotol was first isolated by scientists Asahina and Tsukamoto in 1925. It is one of the primary components found in carrot seed oil comprising approximately 40% of this essential oil. This sesquiterpene alcohol is thought to be formed in carrot seeds (''Daucus carota L., Umbelliferae'') during the vegetation period. Additionally, studies have shown that carotol may be involved in allelopathic interactions expressing activity as an antifungal, herbicidal and insecticidal agent. Biosynthesis It has been proposed that there is a direct cyclisation of farnesyl pyrophosphate (FPP) to the carotol (carotane backbone). This type of cyclisation is unconventional for the typical chemistry of sesquiterpenes. The only other proposed mechanism requires a complex ten-membered ring with a methyl migration. This latter reaction, regardless of how plausible it may appear to be on paper, is energetically undesired, and through the diligent work of M. Soucek and coworkers, it was shown that th ...

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 female mosq ...

Patchouli Alcohol
Patchoulol or patchouli alcohol (C15H26O) is a sesquiterpene alcohol found in patchouli. Patchouli oil is an important material in perfumery. The (−)- optical isomer is one of the organic compounds responsible for the typical patchouli scent. Patchoulol is also used in the synthesis of the chemotherapy drug Taxol. Structure determination Patchouli alcohol was first isolated in 1869 by Gal and its chemical composition later correctly formulated as C15H26O by Montgolfier. During early structural investigation the presence of a saturated tricyclic tertiary alcohol was established. After several years of careful study Büchi and co-workers proposed the structure of patchouli alcohol to correspond to 1, based on degradation studies from his earlier work, verified later by synthesis of material which corresponded to the natural authentic sample of patchouli alcohol. A serendipitous finding by Dunitz and co-workers revealed a contradictory structure. They had undertaken an X-ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
