A Chemical Investigation of Pueraria mirifica Roots

Abstract

Ten isoflavonoids including daidzein, daidzin (daidzein-7-O-glucoside), puerarin (daidzein-8- C-glucoside), genistein and coumestrol have been isolated from a methanolic extract of Pueraria mirifica roots. Apart from these known compounds and mirificin, a novel apioside derivative of puerarin, the roots have also been found to contain three minor coumestans and one 5-deoxyisoflavone for which only limited spectroscopic data are currently available.
