Over 300 different plants contain either compounds with estrogenic activity or precursors for the formation of nonsteroidal estrogens. Coumestrol, equol, and zearalenone are examples of phytoestrogens that are found in legumes, tubers, and fungi that infest grains. These substances clearly act as reproductive toxins in sheep (equol in clover disease) and... 

Reinli and Block (1996) developed a compendium of literature values with 36 references for phytoestrogens (coumestrol, daidzein, genistein, biochanin A and formononetin) in foods. They also reported the relative potency of these phytoestrogen and equol (metabolites found in urine) in vitro and in vivo. Similar to the USDA-ISU database, this database reported total daidzein and genistein, which were estimated by the hydrolysis method or by normalizing the molecular weight differences of...

Equol (49) (Figure 12) of a phytoestrogen is structurally similar to estradiol (17P-estradiol, 7) (Figure 3) was first found in the urine of mares [70, 85] (Figure 15).
