Abstract

Two unusual diglycosides, quercetin and kaempferol 3-rhamnosyl(1----2)galactosides and the new isorhamnetin 3-rhamnosyl(1----2)galactoside have been isolated from the aerial parts of Blackstonia perfoliata. Instead of C-glycosylflavones, the occurrence of flavonol glycosides in this species as well as in three other genera of the Gentianaceae: Centaurium, Coutoubea and Eustoma, is in agreement with the grouping of these four genera in the subtribe Chlorae of the Gentianeae.

摘要

从贯叶金丝桃的地上部分分离出了两种不同寻常的二糖苷，槲皮素和山柰酚3-鼠李糖基（1→2）半乳糖苷以及新的异鼠李素3-鼠李糖基（1→2）半乳糖苷。该物种以及龙胆科其他三个属：百金花属、库图贝属和洋桔梗属中存在黄酮醇苷而非C-糖基黄酮，这与龙胆亚科绿亚族中这四个属的分类一致。
