(-) - α-Bisabolol (synonym: Levomenol ) describes a chemical compound from the series of isomeric bisabolols . There is a monocyclic sesquiterpene - alcohol .
Natural occurrence
(-) - α-Bisabolol is the main component of chamomile oil , which is obtained from the real chamomile ( Matricaria chamomilla ), which is traditionally used as a medicinal plant .
Originally from Spain coming Manzana chamomile , a cultivated form, contains particularly large quantities of Bisabolol (up to 45% of the essential oil) and is therefore now also in countries such as France , Germany and the United States cultivated.
Propolis made by bees can also contain considerable amounts of bisabolol - up to approx. 20% in Chinese / Mongolian propolis.
synthesis
Enantiomerically pure (-) - α-bisabolol is usually obtained from natural sources, although synthetic routes to (-) - α-bisabolol are known; these are often based on nerolidol .
Racemic α-bisabolol, which is also used, is mostly of synthetic origin.
Analytics
For reliable qualitative and quantitative determination of (-) - α-bisabolol, the coupling of gas chromatography with mass spectrometry can be used after adequate sample preparation . Using headspace analysis , these methods are also suitable for detection in various body fluids such as B. blood, urine or tissue samples and faeces .
properties
(-) - α-Bisabolol is a colorless to slightly yellowish, viscous liquid that is insoluble in water, but easily soluble in alcohols and oils. Their smell is described as slightly flowery-sweet.
Effect and use
Bisabolol has an anti-inflammatory effect on the skin and mucous membranes, it is used for skin regeneration and wound healing, for example after burns or sunburn.
These effects have been described both for the enantiomerically pure natural product and for the synthetically accessible racemate.
