Abstract Four flavan-3-ol glycosides and three proanthoeyanidin glycosides have been isolated from the fern, Davallia divaricata , together with procyanidins B-1 and B-2 and a trimeric procyanidin. All of these glycosides have been shown to possess an allopyranose moiety. The structures were elucidated on the basis of chemical and spectroscopic evidence.
摘要 从蕨类植物Davallia divaricata 中分离出4 种黄烷3-醇苷和3 种原花色素苷,以及原花青素B-1 和B-2 以及一种三聚原花青素。所有这些糖苷都已显示出具有别吡喃糖部分。基于化学和光谱证据阐明了这些结构。
