A 2-arylbenzofuran derivative, named mulberrofuran J, was isolated from ethyl acetate extracts of the root bark of cultivated mulberry tree (Morus Lhou(ser.) Koidz.), and its structure was determined to be 1 on the basis of the spectral evidence. Mulberrofuran J is a 3”-stereoisomer on the cyclohexene ring of mulberrofuran C (2) obtained from the root bark of cultivated mulberry tree (Morus alba L. and M. bombysis Koidz .) .
