Description
From the root bark of the cultivated mulberry tree (a variety of Morus alba L.), two new flavones, oxydihydromorusin, kuwanon C, and two flavanones, kuwanon D, kuwanon E, were isolated. Their structures were shown to be VII, VIII, XVIII, and XXI, respectively. For the structures of morusin (I), cyclomorusin (II), compound A (III), VII, and VIII, further evidence was obtained by synthesizing of tetrahydrokuwanon C tetramethyl ether (XVII). Photo-sensitized oxidation of I in the presence of sensitizers afforded III, VI, XXII, and XXIII. The possible mechanism of the formation of these compounds from I was discussed.
