title: Four new prenylated flavonoids from the roots of Cudrania tricuspidata.
abstract: Four new prenylated flavonoids, cudraflavanones E-F (1-2) and cudraflavones F-G (6-7), together with eight known compounds were isolated from the roots of Cudrania tricuspidata. The structures of new compounds were elucidated on the basis of extensive spectroscopic analyses, including 1D and 2D NMR, HRESIMS and CD.
