|Section2= |Section6= }} Eucalyptol is a natural organic compound that is a colorless liquid. It is a cyclic ether and a monoterpenoid. Eucalyptol is also known by a variety of synonyms: 1,8-cineol, 1,8-cineole, cajeputol, 1,8-epoxy-p-menthane, 1,8-oxido-p-menthane, eucalyptol, eucalyptole, 1,3,3-trimethyl-2-oxabicyclo()octane, cineol, cineole. In 1870, F.S. Cloez identified and ascribed the name ''eucalyptol'' to the dominant portion of ''Eucalyptus globulus'' oil. ''Eucalyptus oil'', the generic collective name for oils from the Eucalyptus genus, should not be confused with the chemical compound eucalyptol. ==Composition== Eucalyptol comprises up to 90 percent of the essential oil of some species of the generic product Eucalyptus oil,〔 hence the common name of the compound. It is also found in camphor laurel, bay leaves, tea tree, mugwort, sweet basil, wormwood, rosemary, common sage, cannabis sativa, and other aromatic plant foliage. Eucalyptol with a purity from 99.6 to 99.8 percent can be obtained in large quantities by fractional distillation of eucalyptus oil. Although it can be used internally as a flavoring and medicine ingredient at very low doses, typical of many essential oils (volatile oils), eucalyptol is toxic if ingested at higher than normal doses.〔 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「eucalyptol」の詳細全文を読む スポンサード リンク
