A novel 2-arylbenzofuran derivative, mulberrofuran R, was isolated from an ethyl acetate extract of the root bark of the cultivated mulberry tree (Roso, a cultivated variety of Morus lhou Koidz.). Its structure was shown to be 1, on the basis of spectral evidence. Mulberrofuran R is regarded biogenetically as a variation of a Diels-Alder type adduct of s chalcone derivative and a dehydroprenyl-2-arylbenzofuran derivative.
