Chemical Information
FooDB NameDemethoxycurcumin
DescriptionDemethoxycurcumin, also known as curcuminii or BHCFM, belongs to the class of organic compounds known as curcuminoids. These are aromatic compounds containing a curcumin moiety, which is composed of two aryl buten-2-one (feruloyl) chromophores joined by a methylene group. Demethoxycurcumin is found, on average, in the highest concentration within turmerics (Curcuma longa). Demethoxycurcumin has also been detected, but not quantified in, a few different foods, such as beverages, herbs and spices, and root vegetables. This could make demethoxycurcumin a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Demethoxycurcumin.
