Abstract: The polysaccharides from Phyllostachys pubescens leaves were purified by DEAE-52 cellulose column chromatography and Sephadex G-75 glucan gel column chromatography successively,and a kind of polysaccharide named as BPS11 was obtained. In order to study the physicochemical characteristics of the polysaccharide,ultra violet spectroscopy(UV) ,thin-layer chromatography(TLC) and gas chromatography(GC) were employed. Results showed that the components of the polysaccharide include an unknown monosacchride,rhamnose,arabinose,xylose,mannose,glucose and galatose with contents of 0.50%,4.42%,13.90%,6.63%,11.49%,46.06% and 17.00%,respectively. These are remarkably different from data reported in the past literatures.
