ABSTRACT:

Acid hydrolysis of fully methylated water soluble seeds polysaccharide of Pongamia pinnata Linn. produced certain medicinal chemicals or methyl sugars as 2,3,4,6-tetra-O-methyl-D-glucose; 2,3,4,6-tetra-O-methyl-D-mannose; 2,3,6-tri-O-methyl-D-mannose; 2,3-di-O-methyl-D-mannose and 4,6-di-O-methyl-D-glucose in 1:1:2:1:1 molar ratio. On the basis of above methylated results a chemical structure has been assigned to the seeds polysaccharide.
