Metabolite Identification
Common Name2',6'-Dihydroxy-4'-methoxyacetophenone
Description2',6'-Dihydroxy-4'-methoxyacetophenone, also known as 4-O-methylphloracetophenone, belongs to the class of organic compounds known as alkyl-phenylketones. These are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. 2',6'-Dihydroxy-4'-methoxyacetophenone has been detected, but not quantified in, a few different foods, such as european plums (Prunus domestica), fruits, and sweet oranges (Citrus sinensis). This could make 2',6'-dihydroxy-4'-methoxyacetophenone a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 2',6'-Dihydroxy-4'-methoxyacetophenone.
