Three new flavonoids including two isoflavanones sophortones A and B ( 1 and 2 ), and one chalcone sophortone C ( 3 ) were isolated from the roots of Sophora tonkinensis . Their structures were established by UV, IR, HRESIMS, and NMR data. The absolute configurations of 1 and 2 were determined by electronic circular dichroism (ECD) calculations.
