A new O-prenylated flavonol, 3',4'-dimethoxy-7-(γ,γ-dimethylallyloxy)flavonol (1), together with three known compounds, 2'-hydroxy-3,4-dimethoxychalcone (2), biochanin A (3) and kaempferol-3-O-β-D-glucopyranoside (4), were isolated from the roots of Sophora interrupta Bedd. The structure of compound 1 was elucidated by extensive 1D and 2D NMR spectral studies.
