Biochanin estrogenic activity

Besides the affinity of genistein, daidzein, biochanin A, formononetin, coumestrol and some other flavonoids, there is little information regarding other isoflavones, of which more than 300 have been reported to exist [6], One such example is glycitein, whose estrogenic activity has been reported in one study. The data indicated that glycitein, when fed to female mice at 3 mg/day for 4 days, produced weak estrogenic activity comparable to that of other isoflavones, but much lower than that produced by diethylstilbestrol and 17[3-estradiol [54],... 

A recent study found that mycorrhizal red clover showed impaired levels of isoflavones with estrogenic activity, such as biochanin A, formononetin, genistein, or daidzein [150], and natural plant metabolites called phytoestrogens, which are believed to play an important preventive role in osteoporosis, menopausal... 

Coumestrol, genistein, biochanin A, and daidzein have estrogenic activities on ruminants. Stndies have also demonstrated that coumestrol when fed to pullets increases the age of matnrity and depresses egg...
