Abstract
The objective of this study was to develop a purified Ganoderma polysaccharide for use in prebiotic research. The monosaccharide composition, physicochemical characteristics, and prebiotic activities of the Ganoderma polysaccharides were determined. Additionally, the total protein, total sugar, antioxidant activities, and molecular weights of the polysaccharides were subjected to analysis. The results demonstrated that the purified polysaccharide sample was predominantly composed of short-chain dextrans. The sample was found to comprise trehalose and trace amounts of protein. The Brunauer-Emmet-Teller (BET) analysis revealed that the polysaccharides exhibited a multiporous structure. The polysaccharide structure was found to consist of hydroxyl groups, along with the other common functional groups typically observed in sugar molecules. The polysaccharide sample exhibited moderate thermal stability, and its antioxidant activities were observed to be concentration-dependent. Furthermore, the Ganoderma polysaccharides were observed to facilitate the growth of probiotic strains. Therefore, the polysaccharides are potential nutraceuticals and prebiotics.
期刊介绍：
The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds.
The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal.
Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
