Microstructural Observation of Leucaena glaucal Seed Polysaccharides under Atomic Force Microscope

Abstract

Abstract: Objective: The microstructure of Leucaena glaucal seed polysaccharides was studied based on morphological observation under atomic force microscope (AFM). Methods: Polysaccharides from were extracted by hot water extraction. The structure and morphology of aggregates and non-aggregates from Leucaena glaucal seed polysaccharides formed through varying polysaccharide concentration or chemically modifying the surface of mica substrates were visualized under AFM. Results: Membranous, granular aggregates structure and non-aggregate structure of a single polysaccharide molecule could be observed in the samples prepared at various conditions. Conclusion: A single Leucaena glaucal seeds polysaccharide molecule was linear spiral, and had short branch structure and entangled molecular chains to form a reticulation structure.

Key words: atomic force microscope, Leucaena glaucal seed polysaccharide, microstructure
