摘  要:
将毛竹叶多糖粗提物通过柱色谱进行分离后得到BPS1_1,运用紫外扫描、薄层色谱、气相色谱对BPS1_1的理化性质进行了实验。结果表明,BPS1_1的理化性质与文献报道的结果相似;其单糖组成:未知单糖、鼠李糖、阿拉伯糖、木糖、甘露糖、葡萄糖、半乳糖分别为0.50%、4.42%、13.90%、6.63%、11.49%、46.06%、17.00%,与文献报道结果不同。

摘  要:
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 BPS1_1 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.
