Abstract

Methods were developed for the extraction, fractionation and purification of the more soluble polysaccharides of mustard-seed embryos. 2. One of these components was a pure homopolysaccharide, an araban, which was characterized by analysis, optical rotation, chromatography on diethylaminoethylcellulose and electrophoresis; the hydrolysis products of the methylated polysaccharide were isolated and characterized by the formation of crystalline derivatives. From these studies it emerges that mustard-seed araban is very similar to the family of pectic arabans, except that it is more highly branched than usual and contains a proportion of 1-->2-linkages. 3. A survey of the other polysaccharides of mustard seed, both in the embryos and in the seed coats, suggests a predominance of pectic-type polysaccharides.

摘要

已开发出用于提取、分级分离和纯化芥菜种子胚中更易溶多糖的方法。2. 其中一种成分是一种纯的同多糖，即阿拉伯聚糖，通过分析、旋光、在二乙氨基乙基纤维素上的色谱法和电泳对其进行了表征；甲基化多糖的水解产物被分离出来，并通过形成结晶衍生物进行了表征。从这些研究中可以看出，芥菜种子阿拉伯聚糖与果胶类阿拉伯聚糖家族非常相似，只是它的分支比通常情况更多，并且含有一定比例的1→2连接。3. 对芥菜种子胚和种皮中其他多糖的调查表明，果胶类多糖占主导地位。
