Abstract

Four new isoprenylated xanthones, cudraxanthone H,I,J, and K were isolated from the ethanol extract of the root bark of Cudrania tricuspidata (Carr.) Bur. (Moraceae), collected in China. The structures of cudraxanthones H,I,J, and K were shown to be 1-4, respectively, on the basis of chemical and spectral evidence.
