Abstract

The water-soluble crude extract prepared from Imperata cylindrica (Beauv.) was investigated for its immunomodulating activity. A set of polysaccharides with high molecular weights has been isolated by fractionation using gel filtration and anion-exchange chromatography. Each step of purification was monitored by bioassays. The presence of six monosaccharides has been established by chemical analysis. Quantitative analysis showed that the ratio of these monosaccharides differed from one polysaccharide to another. The crude extract as well as some of the purified polysaccharides enhance the proliferation of murine splenocytes.
