摘要: 以多聚古罗糖醛酸为原料,在稀酸加压条件下进行酸水解得到寡聚古罗糖醛酸混合物,用低压凝胶渗透色谱(LPGPC)和高效液相色谱(HPLC)进行分离纯化,并用荧光基团辅助碳水化合物电泳(FACE)检测纯度.运用IR,ESI/MS/MS,1D,2DNMR等方法对古罗糖醛酸二糖至五糖的化学结构进行了表征.

关键词: 寡聚古罗糖醛酸, 制备, 结构表征

Abstract: The polyguluronic acid obtained from alginate was degraded through acid hydrolysis. The oligosaccharides mixture was fractionated by LPGPC and HPLC methods, and Fluorophore-Assisted-Carbohydrate-Electrophoresis(FACE) was used to confirm their purity. The structure of these oligosaccharides were determined as diguluronic, triguluronic, tetraguluronic and pentaguluronic acids by IR, ESI/MS/MS and 1D, 2D NMR techniques.

Key words: Oligoguluronic acid, Preparation, Structural characterization
