Galactomannan from Grewia oppositifolia Seeds

Abstract

Grewia oppositifolia seeds yielded water-soluble sugars, as

D-galactose and D-mannose, in 2 : 5 moles. It produced methylated

sugars as 2,3,4,6-tetra-O-methyl-D-galacose, 2,3,6-tri-O-methyl-D-mannose;

2,3,6-tri-O-methyl-D-galactose and 2, 3-di-O-methyl-D-mannose

in 1 : 4 : 1 : 1 molar ratio. Periodate oxidation results

showed the consumption of 1.2 moles of periodate with liberation

of 0.25 moles of formic acid.
