Metabolite Identification
Common Name7-Hydroxy-2',3',4'-trimethoxyisoflavan
Description7-Hydroxy-2',3',4'-trimethoxyisoflavan belongs to the class of organic compounds known as 4'-o-methylated isoflavonoids. These are isoflavonoids with methoxy groups attached to the C4' atom of the isoflavonoid backbone. Isoflavonoids are natural products derived from 3-phenylchromen-4-one. 7-Hydroxy-2',3',4'-trimethoxyisoflavan has been detected, but not quantified in, alfalfas (Medicago sativa) and pulses. This could make 7-hydroxy-2',3',4'-trimethoxyisoflavan a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 7-Hydroxy-2',3',4'-trimethoxyisoflavan.
