Although the second biggest terrestrial group of plants, bryophytes remain poorly known chemically compared to the angiosperms. In this article, the sugars of the moss Rhodobryum ontariense, an unstudied representative of the medicinally known genus, are reported. The chemical analysis revealed the usual plant sugar sucrose, and a new sugar, fructooligosaccharide 1-kestose, which is reported first not only for the genus Rhodobryum, but also for mosses. The trisaccharides have been scantily reported in bryophytes hitherto. This gives more significance to this study for further investigation of its role in the moss species. The health-promoting effect of 1-kestose is also briefly discussed.
尽管苔藓植物是地球上第二大植物群体，但与被子植物相比，它们的化学成分仍知之甚少。本文报道了一种未经研究的药用属代表植物——加拿大真藓（Rhodobryum ontariense）中的糖类。化学分析表明，该植物中含有常见的植物糖蔗糖，以及一种新的糖——果寡糖 1-蔗果三糖，这不仅是在 Rhodobryum 属中首次报道，也是在苔藓植物中首次报道。迄今为止，三糖在苔藓植物中报道甚少。因此，本研究对于进一步研究其在苔藓物种中的作用具有更重要的意义。本文还简要讨论了 1-蔗果三糖的促进健康作用。
