Abstract
Two new isoprenylated flavones, cudraflavones A and B were isolated from the root bark of Cudrania tricuspidata (Carr.) Bur. (Japanese name “Hariguwa”, Moraceae). The structures of cudraflavones A and B were shown to be 1 and 2, respectively, on the basis of spectral data. Photo-oxidative cyclization occurred with cudraflavone B leading to the formation of a hydroperoxide possessing a dihydrooxepin ring.This publication has 2 references indexed in Scilit:
