Gum polysaccharide structure from Moringa oleifera Lam. plant gum by methylation technique

Ashish Pal and R. B. Singh

Gum polysaccharide has been extracted from Moringa oleifera Lam. plant gum (Moringaceae) with water as Larabinose and D-galactose in 1:4 molar ratio with traces of L-fructose. The purified gum polysaccharide was completely methylated by Hakomari and Purdie’s method which afforded methyl sugars as : 2,3,4,6-tetra-O-methyl- D-galactose; 2,3,4-tri-O-methyl-D-galactose; 2,4-di-O-methyl-D-galactose and 2,2-di-O-methyl-L-arabinose were found in the molar ratio of 1:1:2:1 and also present uronic acid as : 2,3,4-tri-O-methyl-D-glucuronic acid (1 mole).
