Chemical Information
FooDB Namebeta-Thujaplicin
Descriptionbeta-Thujaplicin, also known as hinokitiol or β-thujaplicin, belongs to the class of organic compounds known as tropolones. Tropolones are compounds containing tropone ring with a hydroxyl group at ring position 2. beta-Thujaplicin is an extremely weak basic (essentially neutral) compound (based on its pKa). beta-Thujaplicin is a phenolic and woody tasting compound. beta-Thujaplicin has been detected, but not quantified in, fruits. This could make beta-thujaplicin a potential biomarker for the consumption of these foods.
