When a solution of morusin (I) was exposed to bright sunshine or irradiated with a high-prssure mercury lamp, morusin hydroperoxide (III) was obtained in a high yield. This reaction did not occur in the dark. The reaction was dependent on the solvent and proceeded in chloroform or benzene solution whereas the starting material was recovered unchanged in methanol, ethanol or tert-butyl alcohol solution. Both of the free hydroxyl group at C_2' and the isolated double bond of the γ, γ-dimethylallyl group attached to the 3-position of flavone were found to be required for this photooxidation. Reduction of III gave compound A (II) which had been isolated from the root bark of Morus alba L. On the basis of these findings, the structure of morusin hydroperoxide was shown to be III.
