Metabolite Identification
Common Name4',7-Dihydroxy-2'-methoxy-3'-prenylisoflavan
Description4',7-Dihydroxy-2'-methoxy-3'-prenylisoflavan belongs to the class of organic compounds known as 2'-o-methylated isoflavonoids. These are isoflavonoids with methoxy groups attached to the C2' atom of the isoflavonoid backbone. Isoflavonoids are natural products derived from 3-phenylchromen-4-one. Thus, 4',7-dihydroxy-2'-methoxy-3'-prenylisoflavan is considered to be a flavonoid. 4',7-Dihydroxy-2'-methoxy-3'-prenylisoflavan has been detected, but not quantified in, cowpeas (Vigna unguiculata) and pulses. This could make 4',7-dihydroxy-2'-methoxy-3'-prenylisoflavan a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on 4',7-Dihydroxy-2'-methoxy-3'-prenylisoflavan.
