Abstract

Two new prenylflavones, cudraflavones C (1) and D (2), along with six known compounds were isolated from the root bark of Cudrania tricuspidata (Carr.) Bur. (Moraceae), collected in China. The structures of cudraflavones C and D were shown to be 1 and 2, respectively, on the basis of spectroscopic data.
