title: Caffeoyl, coumaroyl, galloyl, and hexahydroxydiphenoyl glucoses from Balanophora japonica.
abstract: Eighteen new and sixteen known acyl glucoses having caffeoyl, coumaroyl, galloyl, and hexahydroxydiphenoyl groups were isolated from a medicinal parasitic plant, Balanophora japonica. Their structures were determined by spectroscopic and chemical methods. Caffeoyl ellagitannins, which have been rarely found in nature, were major phenolic constituents of this plant, and this is the first report of the isolation of ellagitannins from Balanophoraceae.
