从葡萄属葡萄（Viniferifuran）中分离得到三个新的含苯并呋喃结构的低聚芪类化合物：viniferifuran，（+）-vitisifuran A和（-）-vitisifuran B。通过光谱和化学方法确定了它们的结构，包括绝对构型。此外，它们分别由绝对构型已知的（+）-ε-葡萄糖苷、（+）-葡萄素A和（-）-葡萄素B化学转化而来。(C)1999爱思唯尔科技有限公司。保留所有权利。
Three new oligostilbenes having a benzofuran moiety, viniferifuran, (+)-vitisifuran A and (-)-vitisifuran B, were isolated from Vitis vinifera 'Kyohou'. The structures of these oligostilbenes including the absolute configuration were elucidated by spectroscopic and chemical methods. Furthermore, these were chemically transformed from (+)-epsilon-viniferin, (+)-vitisin A and (-)-vitisin B, respectively, whose absolute configurations are known. (C) 1999 Elsevier Science Ltd.
