Metabolite Identification
Common Name6-Methoxymellein
Description6-Methoxymellein, also known as 6-MHMD-isocoumarin, belongs to the class of organic compounds known as 2-benzopyrans. These are organic aromatic compounds that 1-benzopyran, a bicyclic compound made up of a benzene ring fused to a pyran, so that the oxygen atom is at the 2-position. 6-Methoxymellein has been detected, but not quantified in, a few different foods, such as carrots (Daucus carota ssp. sativus), root vegetables, and wild carrots (Daucus carota). This could make 6-methoxymellein a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on 6-Methoxymellein.
