Abstract
Water soluble polysaccharide was prepared from Iraq dates. Slightly yellow powder was obtained by successive extraction with aqueous solution of phenol, trichloroacetic acid and pyridine and was purified by dialysis. This substance was isolated as electrophoretically single compound, positive to the Molisch reaction, negative to biuret reaction, and contained no nitrogen. Hydrolysis of this polysaccharide gave three monosaccharides, xylose, arabinose and galactose. This polysaccharide afforded electrophoretically single polysaccharide with molecular weight of ca. 6500 per one terminal group. By the method of Archibald the molecular weight of this polysaccharide was calculated as 6800_??_8000.
