Abstract: | Three new flavonoids isoprenylated as 2,2-dimethyl-dihydropyran groups, named sophoranodichromanes A-C (1-3), have been isolated from the roots of Sophora flavescens, together with the known compounds, chrysophanol (4), soyasapogenol B (5) and β-sitosterol (6). Their structures have been elucidated by spectroscopic methods. |
