摘要：
Three new isoflavanones, secundiflorols D-F, were isolated from the roots of Sophora secundiflora in addition to the nine known flavonoids, geraldol, pseudobaptigenin, pratensein, formononetin, calycosin, secundifloran and secundiflorols A-C. The structures of secundiflorols D-F were established as 5'-alpha,alpha-dimethylallyl-7,2',3'-trihydroxy-4'-methoxyisoflavanone, 5'-alpha,alpha-dimethylallyl-5,7,3'-trihydroxy-2',4'-dimethoxyisoflavanone and (3R)-2'-gamma,gamma-dimethylallyl-7,3'-dihydroxy-4'-methoxyisoflavanone, respectively, by means of spectral evidence.
