The present study reports the presence of a β-D-fructopyranosyl-(2→1)-linked fructan in nature for the first time, with a β-D-fructofuranosyl-(2→1)-linked fructan in a mixture from Codonopsis pilosula. High-performance gel permeation chromatography (HPGPC) shows that the molecule weights of these two fructans are 2.33 and 1.31 kDa. Their structures were analyzed by 1D and 2D NMR.

党参根的果聚糖

本研究首次报告了自然界中存在β -D-吡喃果糖基-(2→1)-连接的果聚糖，以及党参混合物中的β -D-呋喃果糖基-(2→1)-连接的果聚糖党参。高效凝胶渗透色谱 (HPGPC) 显示这两种果聚糖的分子量分别为 2.33 和 1.31 kDa。它们的结构通过一维和二维核磁共振分析。
