galacto mannan composed of n-galactose (1 mol)and D-~W~MOSZ (2 mol)was isolated from the seed of Delonix regiu. Hydrolysis of rnethylated galactomarkn yielded 2,3,4,6-tetra-O-methyl-o-galactose (l-02 mol). 2.3,~tri-O-methyl-D-mannose (1.05 mol)and 2,3-di-0-methyl-D-mannose (1 mol). The periodate consumption was l-30 mol.for each hexo.se unit with concomitant liberation of O-31 mol -of formic acid. Hydrolysis of the reduced oxopolysaccharide gave only glycerol (1 mol)and erythritol (1.04 mol). It is established that galactomannan is a highly branched polysaccharide consisting of the main chain of ma~ose united linked through p (l-+4)and side chain of single galactose units linked through a (1+6).
