摘要
从中药胖大海水提取液中分离纯化得水溶性多糖PPⅢ。它由半乳糖、阿拉伯糖、鼠李糖组成,摩尔比为1:1.67:1.01,分子量16.22万。分子主链中鼠李糖之间通过α-(1→3)甙键连接。它的主片段PPⅢ由半乳糖和鼠李糖组成,摩尔比为1:2.78,分子量为6.25万。
Polysaccharide PP Ⅲ was isolated and purified from aqueous extract of the seeds of Sterculia ly-chnophora.It is composed of galactose,arabinose and rhamnose,the molar ratio being 1:1.67:1.01 and molecularweight 162200.Rhamnoses in the main chain are linked by a (1→3)glycoside linkage.PPⅢ C is its major fragment,and is composed of galactose and rhamnose with a molar ratio of 1:2.78 and MW 62500.
