Metabolite Identification
Common NameFormononetin
DescriptionFormononetin, also known as biochanin b, belongs to the class of organic compounds known as 4'-o-methylisoflavones. These are isoflavones with methoxy groups attached to the C4' atom of the isoflavone backbone. Thus, formononetin is considered to be a flavonoid. Based on a literature review a significant number of articles have been published on Formononetin.
