Abstract

Four new isoprenylated xanthones, cudraxanthones A, B and C were isolated from the n-hexane extract of the root bark of Cudrania tricuspidata (Carr.) Bur. (Japanese name “Hariguwa”; Moraceae), and cudraxanthone D from the benzene extract. The structures of cudraxanthones A, B, C and D were shown to be 1-4, respectively, on the basis of spectral and chemical evidence.
