• Beschreibung

  Nerolidol has a faint, floral odor similar to rose and apple. It is an unusually sweet, fresh, tenacious odor. The natural product can be dextro- or levo-rotatory, whereas the synthetic product is optically inactive; the double bond at positions 6-7 accounts for the cis- and trans-forms.

• Chemische Eigenschaften

  Nerolidol is the sesquiterpene analog of linalool. Because of the double bond at the 6-position, it exists as (6Z)- and (6E)- isomers, each forming an enantiomeric pair, since the carbon atom in the 3-position is asymmetric. Nerolidol is a component of many essential oils. (3S,6E)-(+)-nerolidol occurs in cabreuva oil.
  Synthetic nerolidol consists of a mixture of racemic (6Z)- and (6E)-nerolidol and is a colorless liquid with a long-lasting, mild floral odor. Industrial synthesis of nerolidol starts with linalool, which is converted into geranylacetone by using diketene, ethyl acetoacetate, or isopropenyl methyl ether, analogously to the synthesis of 6-methyl-5-hepten-2-one from 2-methyl- 3-buten-2-ol. Addition of acetylene and partial hydrogenation of the resultant dehydronerolidol produces a mixture of (6Z)- and (6E)-nerolidol racemates.Nerolidol is used as a base note in many delicate floral odor complexes. It is also an intermediate in the production of vitamins E and K₁.

• Verwenden

  Nerolidol is one of the main component in the essential oils from fresh aerial parts of Thymus ciliatus (Lamiaceae). Also, it is a terpene that displays high potency on the contractility of cardiac muscle in guinea pig left atrium. A potential and effective treatment for malaria.

• Verwenden

  anti-ulcer, insect antifeedant

• synthetische

  1) From Geranylacetone plus Acetylene, followed by reduction of the acetylenic linkage (HotTmann-laRoche process).
  2) by isolation from Cabreuva oil or other essential oils.
  

• Definition

  ChEBI: Nerolidol is a farnesane sesquiterpenoid that is dodeca-1,6,10-triene which carries methyl groups at positions 3, 7 and 11 and a hydroxy group at position 3. It is a natural product that is present in various flowers and plants with a floral odor. Chemically, it exists in two geometric isomers, trans and cis forms. It is widely used in cosmetics (e.g. shampoos and perfumes), in non-cosmetic products (e.g. detergents and cleansers) and also as a food flavoring agent. It has a role as a flavouring agent, a cosmetic, a pheromone, a neuroprotective agent, an antifungal agent, an anti-inflammatory agent, an antihypertensive agent, an antioxidant, a volatile oil component, an insect attractant and a herbicide. It is a farnesane sesquiterpenoid, a tertiary allylic alcohol and a volatile organic compound.

• Aroma threshold values
