Confirmation of seeds cake polysaccharide structure from Madhuca longifolia Linn. Plant by periodate oxidation studies

Abstract

Periodate oxidation is one of the most important reaction in the structural study of the non-ionic seeds polysaccharide. Periodate oxidation was done using with sodium metaperiodate as oxidant. It consumed 3.55 moles of periodate with simultaneous liberation of 1.45 moles of formic acid per mole of anhydrohexose sugar unit after 165 hrs. The isolated water soluble seeds cake polysaccharide as D-glucose and D-mannose were present in 7:4 molar ratio. The proposed polysaccharide structure from Madhuca longifolia Linn. seeds have been elucidated with methylation results was confirmed by the periodate oxidation results.
