Bisabolol, or more formally α-(−)-bisabolol or also known as levomenol,〔(Rohstoff-Lexikon Bisabolol )〕 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''.〔(Bisabolol (in english) )〕 It is almost insoluble in water and glycerin, but very 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. 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 perceived skin healing properties. Bisabolol is known to have anti-irritant, anti-inflammatory and anti-microbial properties. Bisabolol is also demonstrated to enhance the percutaneous absorption of certain molecules.〔J Am Oil Chem Soc (2010) 87;1-7.〕 α-bisabolol has recently been shown to induce apoptosis in models of leukemia. A structurally related compound known as β-bisabolol (CAS registry number ()) differs only in the position of the tertiary alcohol functional group. ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bisabolol」の詳細全文を読む スポンサード リンク
