Abstract
Three new isoflavanones, secundiflorols D-F, were isolated from the ro ots of Sophora secundiflora in addition to the nine known flavonoids, geraldol, pseudobaptigenin, pratensein, formononetin, calycosin, secun difloran and secundiflorols A-C. The structures of secundiflorols D-F were established as ylallyl-7,2',3'-trihydroxy-4'-methoxyisoflavanone, llyl-5,7,3'-trihydroxy-2',4'-dimethoxyisoflavanone and methylallyl-7, 3'-dihydroxy-4'-methoxyisoflavanone, respectively, by means of spectra l evidence.
