Metabolite Identification
Common Name2'-Hydroxy-4',6'-dimethoxychalcone
Description2'-Hydroxy-4',6'-dimethoxychalcone, also known as 4',6'-dimethoxy-2'-hydroxychalcone, belongs to the class of organic compounds known as 2'-hydroxychalcones. These are organic compounds containing chalcone skeleton that carries a hydroxyl group at the 2'-position. Thus, 2'-hydroxy-4',6'-dimethoxychalcone is considered to be a flavonoid. 2'-Hydroxy-4',6'-dimethoxychalcone has been detected, but not quantified in, beverages. This could make 2'-hydroxy-4',6'-dimethoxychalcone a potential biomarker for the consumption of these foods. 2'-Hydroxy-4',6'-dimethoxychalcone is a secondary metabolite.
