Abstract

Three new flavonol triglycosides quercetin, kaempferol and isorhamnetin 3-rhamnosyl(1----2)galactoside-7-glucosides have been isolated from leaves and stems of Blackstonia perfoliata. This species together with three other genera of the tribe Gentianeae, subtribe Chlorae: Centaurium, Coutoubea and Eustoma, is unusual in producing flavonol glycosides instead of C-glycosyl flavones, the more characteristic flavonoid constituents of the Gentianaceae.

摘要

从贯穿叶金丝桃的叶和茎中分离出了三种新的黄酮醇三糖苷，即槲皮素、山奈酚和异鼠李素3 - 鼠李糖基（1→2）半乳糖苷 - 7 - 葡萄糖苷。该物种与龙胆族绿龙胆亚族的其他三个属，即百金花属、库图贝属和洋桔梗属一样，不同寻常之处在于其产生的是黄酮醇苷而非C - 糖基黄酮，而C - 糖基黄酮是龙胆科更具特征性的黄酮类成分。
