摘要：

By further investigation on the constituents of roots of Echinosophora koreensis, three novel flavanones with a 2',4',6'-trioxygenated B ring were isolated. These structures were determined to be (2R,3R)-8-gamma,gamma-dimethylallyl-6-geranyl-5,7,2',6'-tetrahydroxy-4'-methoxyflavanone (kenusanone C), (2S)-8-gamma,gamma-dimethylallyl-5,7,2',6'-tetrahydroxy-4'-methoxyflavanone (kenusanone D) and (2S)-8-gamma,gamma-dimethylallyl-5,2',6'-trihydroxy-7,4'-dimethoxyflavanone (kenusanone E), respectively, by spectroscopic analysis. The characteristic behaviour of H-2 and H-3 in a 2',6'-dioxygenated flavanone or flavanonol is also discussed.
