Rectified oils have been redistilled to improve a particular property or characteristic, such as flavor or aroma. Eor example, natural oil of peppermint is frequently rectified to remove dimethyl sulfide, which has a powerful and objectionable cooked vegetable note deleterious to the use of the oil in cmme de menthe Hqueurs. Distillation is also used to remove psoralens, which are harmful photosensitizing agents present in natural bergamot oil. Color may be removed, eg, from cassia oil, by vacuum steam distillation. A desirable component, such as 1,8-cineole (eucalyptol) 85% in eucalyptus oil, may be... 

Menthol is widely used in pharmaceuticals, confectionery, and toiletry products as a flavoring agent or odor enhancer. In addition to its characteristic peppermint flavor, /-menthol, which occurs naturally, also exerts a cooling or refreshing sensation that is exploited in many topical preparations. Unlike mannitol, which exerts a similar effect due to a negative heat of solution, /-menthol interacts directly with the body s coldness receptors. d-Menthol has no cooling effect, while racemic menthol exerts an effect approximately half that of /-menthol. 

The flavors and scents of nature include many examples of alcohols and ethers. Menthol, found in peppermint oil, is an alcohol used both for flavoring and for medicinal purposes. Vanillin, isolated from vanilla beans, contains an ether functional group, as does anethole, the licorice flavor associated with fennel. Ethanol, the alcohol produced by fermentation, is, of course, another flavor of nature. Borneol, which can be isolated from artemesia, is an alcohol with a fascinating molecular architecture. And eucalyptol, which shares the ending of its name with other alcohols but is actually an ether, comes from eucalyptus leaves (shown in the left photo above) and is used as a flavoring, scent, and medicinal agent Nature is an abundant source of alcohols and ethers, and we study the chemistry of these important functional groups in this chapter.
