Metabolite Identification
Common NameDehydro-1,8-cineole
DescriptionDehydro-1,8-cineole belongs to the class of organic compounds known as pyrans. Pyrans are compounds containing a pyran ring, which is a six-member heterocyclic, non-aromatic ring with five carbon atoms, one oxygen atom and two ring double bonds. Dehydro-1,8-cineole is a lemon and mint tasting compound. Dehydro-1,8-cineole has been detected, but not quantified in, several different foods, such as herbal tea, teas (Camellia sinensis), red tea, sweet bays (Laurus nobilis), and green tea. This could make dehydro-1,8-cineole a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Dehydro-1,8-cineole.
