摘要/Abstract

摘要： 将野皂荚豆中分离出的多糖胶加以提纯,对其化学、物理性质进行了研究,提纯的多糖是均匀的。经测定,多糖是由半乳糖和甘露糖组成,其配比为 1:3.2,化学结构为:主链以 β-(1,4)-苷键连接的D-吡喃甘露糖和支链以α-(1,6)-苷键连接的D-吡喃半乳糖。

关键词: 野皂荚胶, 半乳甘露聚糖

Abstract: Polysaccharide is isolated and purified from seeds of G.heterophylla Bunge and its physiochemical properties are investigated.The purified polysaccharide is homogeneous.It is determined to be consisted of D-galactose and D mannose at ratio 1:3.2 with the chemical structure of β-(1,4)-linked D-mannopyranosy1 residues as the main chain and α-(1,6)-linked D-galactopyranosy1 residues in the side chain.

Key words: Gleditsia heterophylla gum, galactomann
