Abstract

From the ethyl acetate extract of the root bark of the cultivated mulberry tree (a variety of Morus alba L.), a novel flavone derivative, moracenin D, containing condensed dihydrochalcone partial structure was isolated. The structure was shown to be I on the basis of the formation of moracenin D (I) from kuwanon G (II).
