What is the density of isoborneol?
1.01 g/cm³Borneol / Density
What is the source of borneol?
Natural borneol is mainly extracted from the essential oils of numerous medicinal plants of the families Dipterocarpaceae (for example, Dipterocarpus turbinatus tree), Lamiaceae (for example, Rosmarinus officinalis or Salvia officinalis), Valerianaceae (for example, Valeriana officinalis) or Asteraceae (for example.
Is borneol organic?
(-)-Borneol, also known as L-borneol or linderol, belongs to the class of organic compounds known as bicyclic monoterpenoids. These are monoterpenoids containing exactly 2 rings, which are fused to each other. Based on a literature review a small amount of articles have been published on (-)-Borneol.
Is borneol soluble in water?
Borneol appears as a white colored lump-solid with a sharp camphor-like odor. Burns readily. Slightly denser than water and insoluble in water.
What is difference between isoborneol and borneol?
An alcohol (borneol) is being oxidized into a ketone (camphor). A subsequent reduction takes us back to another alcohol (isoborneol), which is an isomeric form of the original.
Why is borneol more stable than isoborneol?
activation energy than what is required to turn camphor into borneol. Though borneol is the more stable product, the energy requirements to form isoborneol are lower because the borohydride is adding to the less sterically hindered point on the carbonyl carbon. The product made is then mostly (85%) isoborneol.
What is borneol soluble in?
Leaves from ligroin; MP 206 °C; BP 213 °C; density: 1.011 g/cu cm at 20 °C. Insoluble in water; very soluble in ethanol, ether, benzene /Borneol, (+/-)-/
How many chiral centers are in borneol?
Notice that there are actually 3 chiral centers in the (1S)-[endo]-(1)-borneol substrate.
How do you oxidize borneol?
An alcohol (borneol) is being oxidized into a ketone (camphor). A subsequent reduction takes us back to another alcohol (isoborneol), which is an isomeric form of the original. The oxidizing agent in the first step is sodium hypochlorite, which is present in commercial bleach as an aqueous solution.
How many diastereomers does borneol have?
Chemically synthesized borneol contains four different borneol stereoisomers. There is no regulation to differentiate above two borneol products in Taiwan.
Is borneol Endo or Exo?
The two product stereoisomers are called borneol (from exo attack) and isoborneol (from endo attack).
What is borneol used for?
A staple of Asian traditional medicine, borneol is an effective anti-inflammatory and pain reliever, primarily as a topical. Borneol has also proven effective as an anticoagulant for stroke patients, and may increase the effectiveness of other drugs. What is borneol?
What is the difference between borneol and laevo-borneol?
Borneol is a component of many essential oils and it is a natural insect repellent. It also generates a TRPM8 -mediated cooling sensation similar to menthol. Laevo-borneol is used as an aroma chemical in perfumery. It has a balsamic odour type with pine, woody and camphoraceous facets.
What is borneol made from?
It is one of the chemical compounds found in castoreum. This compound is gathered from the beaver’s plant food. Borneol can be synthesized by reduction of camphor by the Meerwein–Ponndorf–Verley reduction (a reversible process).
What is the scientific name of borneol?
One historical name for borneol is Borneo camphor which explains the name. The compound was named in 1842 by the French chemist Charles Frédéric Gerhardt. Borneol can be found in several species of Heterotheca, Artemisia, Callicarpa, Dipterocarpaceae, Blumea balsamifera and Kaempferia galanga.
