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
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.
