Chemical Information
FooDB NameL-Quebrachitol
DescriptionL-Quebrachitol belongs to the class of organic compounds known as cyclohexanols. Cyclohexanols are compounds containing an alcohol group attached to a cyclohexane ring. L-Quebrachitol is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, L-Quebrachitol is found, on average, in the highest concentration within sea-buckthornberries. L-Quebrachitol has also been detected, but not quantified in, mugworts. This could make L-quebrachitol a potential biomarker for the consumption of these foods. It is also found in Cannabis sativa, in Paullinia pinnata and in seabuckthorn. For example, its conversion into antifungal (E)-β-methoxyacrylate, oudemansin X has been made. It shows a sweetening property half of that of sucrose but induces colic or diarrhoea at concentration used to render the food palatable. Quebrachitol is a versatile building block in the construction of naturally occurring bioactive materials. It can be found in Allophylus edulis and in the serum left after the coagulation of the Hevea brasiliensis latex in the operation of rubber tapping. It was first isolated by Tanret in 1887 from the bark of Aspidosperma quebracho. The substance was tested as a sweetening agent for diabetics in 1933. Quebrachitol is a naturally occurring optically active cyclitol, a cyclic polyol.
