Abstract

Four new isoprenylated xanthones, cudraxanthones L, M, N, and O were isolated from the ethanol extract of the root bark of Cudrania tricuspidata (Carr.) Bur. (Moraceae), collected in China. The structures of cudraxanthones L, M, N, and O were shown to be 1-4, respectively, on the basis of chemical and spectral evidences.
