Abstract

Two tri-, two hexa- and two deca-saccharides were isolated from bear milk by chloroform/methanol extraction and gel filtration. The oligosaccharides were characterized, mainly by 1H-NMR, as follows: [structures: see text]. Both trisaccharides were present in bear milk at a higher concentration than lactose.

摘要

通过氯仿/甲醇萃取和凝胶过滤从熊奶中分离出两种三糖、两种六糖和两种十糖。这些寡糖主要通过¹H-NMR进行表征,结构如下:[结构:见原文]。熊奶中两种三糖的浓度均高于乳糖。
