内容記述 | Nupharanin (1), the first ellagitannin with dehydrohexahydroxydiphenoyl esters at the 1,4-positions of a-D-glucose, was isolated from the fresh rhizome of Nuphar japonicum. Based on spectroscopic evidence,the structure was determined to be 1,4-(S)-dehydrohexahydroxydiphenoyl-2-galloyl-3,6-(R)-hexahydroxydiphenoyl- a-D-glucopyranose. The structure was supported by spectroscopic studies of acetonyl derivatives of 1 and its partial hydrolysate. In addition, unusual oxidative cleavage of the hydrated cyclohexenetrione ring of 1 was observed on moderate heating at 50 C in pH 6 buffer. |
