Study on Constitutes,Separation and Purification Technology of Yam Polysoccharides

Abstract

Abstract: This paper studied the separation technics of the yam polysaccharides.The results showed the optimum conditions to separate the polysaccharide are:S/W 1:25,tempetrature 100 ℃ and time 2.5 h.During the next purification step,three kinds of polysaccharides are found,including one neutral polysaccharide and two acid polysaccharides.The GC-MS results showed that the neutral polysaccharide includes glucose and mannose,but acid polysaccharide 1 includes glucose,mannose and galactose,acid polysaccharide 2 includes glucose,mannose arabinose,xylose and altrose.

Key words: polysaccharide, purification, GC-MS
