Cistanche polysaccharides enhance echinacoside absorption in vivo and affect the gut microbiota.
The polysaccharides and phenylethanoid glycosides from Cistanche deserticola have been demonstrated with various health benefits, however the interactive effect between these two kinds of compounds in vivo are not in detail known. The objective of this study was to investigate the synergistic actions of cistanche polysaccharides with phenylethanoid glycoside and the effects of polysaccharides on gut microbiota. Sprague-Dawley rats were fed with different kinds of cistanche polysaccharides for 20 days, on the last day, all rats were administered the echinacoside at 100 mg/kg. The results were compared mainly on the difference of pharmacokinetic parameters, gut microbiota composition, and short chain fatty acids contents. The results indicated that all the cistanche polysaccharides, including crude polysaccharide, high molecular weight polysaccharide and low molecular weight polysaccharide, could regulate the gut microbiota diversity, increase beneficial bacteria and particularly enhance the growth of Prevotella spp. as well as improve the production of short chain fatty acids and the absorption of echinacoside. By exploring the synergistic actions of polysaccharides with small molecules, these findings suggest that cistanche polysaccharides, particularly low molecular weight polysaccharides, could be used as a gut microbiota manipulator for health promotion.
