Daidzein 486-66-8

Daidzein belongs to the isoflavone clavonoids.it is also classifled as a phytoestrogen since it is a plant-derived nonsteroidal compound that possesses estrogen-like biological activity.Daidzein has been found to have both weak estrogenic and anti-estrogenic effects. Daidzein is the aglycone(aglucon) of daidzein.The isoflavone is found naturally as the glycosides 6"-O-malonylgenistin and 6"-O-acetyldaidzin. Daidzein and its glycosides are mainly found in legumes, such as soybeans and chickpeas. Soybeans and soy foods are the major dietary sources of these substances. Daidzein glycosides are the second most abundant isoflavones in soybeans and soy foods; genistein glycosides are the mostabundant.Nonfermented soy foods, such as tofu, contain daidzein, principally in its glycoside forms. Fermented soy foods, such as tempeh and miso, contain significant levels of the aglycone.
