Metabolite Identification
Common NameAlfalone
DescriptionAlfalone belongs to the class of organic compounds known as 7-o-methylisoflavones. These are isoflavones with methoxy groups attached to the C7 atom of the isoflavone backbone. Thus, alfalone is considered to be a flavonoid. Alfalone has been detected, but not quantified in, alfalfas (Medicago sativa) and pulses. This could make alfalone a potential biomarker for the consumption of these foods. Based on a literature review a small amount of articles have been published on Alfalone.
