Three new ellagitannins named balanophotannins A-C having a 1,1'-(3,3',4,4'-tetrahydroxy)dibenzofurandicarboxyl group in their molecules and four known lignan glycosides were isolated from the extracts of fresh aboveground and underground parts of a medicinal parasitic plant Balanophora japonica (Balanophoraceae). Their structures were elucidated on the basis of spectral and chemical evidence. Chemotaxonomic significance of the known lignan glycosides in Balanophora japonica was discussed.
从药用寄生植物日本蛇菰(蛇菰科)新鲜地上和地下部分的提取物中,分离出三种新的鞣花单宁,命名为蛇菰鞣花单宁A - C,其分子中含有1,1'-(3,3',4,4'-四羟基)二苯并呋喃二甲酰基,以及四种已知的木脂素糖苷。基于光谱和化学证据阐明了它们的结构。讨论了日本蛇菰中已知木脂素糖苷的化学分类学意义。
