phytoestrogens and sophoricoside

The naringinase-treated methanol extract of Sophora japonica L. (Fabaceae) seeds showed potent estrogen agonist activity. Through bioassay-guided isolation of the main active constituents from the naringinase-treated methanol extract of S. japonica, the aglycones genistein and kaempferol were found to be the main phytoestrogens in the naringinase-treated extract. In addition, kaempferol was nearly equipotent to genistein as an estrogen agonist. Concerning the compounds isolated from the untreated methanol extract, sophoricoside showed weak estrogenic activity on ERbeta only.
