Preparation, characterization and improvement in intestinal function of polysaccharide fractions from okra

The purpose of this study was to investigate the effect of okra polysaccharides with similar molecular weight on intestinal ecology. After extraction, ethanol precipitation, deproteinization and purification, two polysaccharide fractions, named as water-extracted polysaccharides (WEP) and alkaline-extracted polysaccharides (AEP), were obtained. According to the results of high performance liquid chromatography, AEP contained mannose, rhamnose,...
