Metabolite Identification

Common Name

beta-O-Methylynephrine

Description

beta-O-Methylynephrine belongs to the class of organic compounds known as benzylethers. These are aromatic ethers with the general formula ROCR' (R = alkyl, aryl; R'=benzene). beta-O-Methylynephrine has been detected, but not quantified in, citrus. This could make beta-O-methylynephrine a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on beta-O-Methylynephrine.
