摘要：
Soybean seedlings and therefrom extractable compositions are described. Such compositions comprise prenylated isoflavones and at least one isoflavonoid, said isoflavonoid being selected from one of the chemical classes of isoflavones, coumestans and pterocarpans. Such compositions usually comprise at least 5% prenylated isoflavones, in particular prenylated isoflavones selected from prenylated daidzein, prenylated hydroxydaidzein, prenylated glycitein, prenylated hydroxygenistein, and prenylated genistein. Such compositions also comprise pterocarpans, preferably in amounts of at least 20%, and with a novel ratio of glyceollin I to glyceollin II to glyceollin III to glyceollin IV. Also described is a production method comprising the step of fermenting the soybeans under stress, in particular in the presence of cultures of fungi, preferably in the presence of Rhizopus microsporus Var. oryzae.
