[Components of Root Bark of Morus australis.].
In addition to mulberrofuran D, a new 2-arylbenzofuran derivative, six flavone derivatives, morusin, oxydihydromorusin, cyclomorusin, kuwanon C, G and H, were isolated from extracts of root bark of MORUS AUSTRALIS P OIR. The structure of mulberrofuran D was shown to be 5 on the basis of spectral and chemical data. Mulberrofuran D is the first example of a geranylated and prenylated 2-arylbenzofuran derivative found in nature.
