A new prenylated flavanonol, (2R,3R)-8-isopentenyl-5-methoxy-7,2′,4′-trihydroxyflavanonol (1) was isolated from the roots of Sophora flavescens. The structure was elucidated on the basis of spectroscopic data. Compound 1 exhibited moderate inhibition towards HeLa, HepG2, and HL-60 tumor cell lines at 14.3, 19.2, 31.5 μg/mL, respectively.
