- 16 Photooxidation of Prenylflavones Isolated from the Root Bark of Morus alba L.
抄録
The structures of five new flavone derivatives, morusin, cyclo-morusin, compound A, kuwanone A, and kuwanone B, which had been isolated from the root bark of the cultivated mulberry tree (a kind of Morus alba L.), were shown to be I, II, III, IV, and V, respectively. During the course of the study, we had encountered an unusual photooxidation of morusin (I), When a solution of I in CHCl_3 was exposed to bright sunshine, hydroperoxide (IX) was obtained in very high yield. The structure (IX) of this hydroperoxide was determined from chemical and spectral analysis. The mechanism of this reaction was discussed and the phenoxy radical (XV) was suggested to be the intermediate of this photooxidation.
