The results of study on enrichment of heavy metal Pb2+ in water show that the water can be purified by Alternanthera philoxeroides.

水花生对水体中重金属Pb2+的富集作用研究表明，重金属Pb2+浓度为5mg／L，pH为7.0-8.0 (pH为7.5最佳)，处理温度为25℃-30℃(温度25℃最佳)时；在处理时间为7d以后，水花生净化Pb2+可以达到低于国家标准所允许排放的最高浓度0.2mg／L

Nepalensis wall polysaccharide was prepared with hot water extraction,ethanol precipitation,dialyzation,and lyophilization.the crude polysaccharide was separated by deae-cellulose chromatography and purified by sephadex g-200 chromatography.the inhibit effect of the polysaccharide on lipid peroxidation of mice liver was conducted by tba method.the model of liver-injury induced by carbon tetrachloride（ccl4was used to validate the variety of the realated ast.results onefold ingredient polysaccharide was obtained after isolated and purified.conclusion the ingredient can remarkably inhibit lipid peroxidation of rat liver and significantly reduce activity of ast.

用热水提取，乙醇沉淀提取粗多糖，再经sevag法去除蛋白，透析去除小分子物质，冷冻干燥得楮头红多糖粗品；采用deae-52纤维素柱层析和sephadex g-200凝胶柱层析进行分离纯化；用tba法考察多糖的抗脂质过氧化作用；采用ccl4急性肝损伤模型，测定其血清中ast变化。结论获得一个楮头红多糖组分。tba法表明该组分对小鼠自发性脂质过氧化具有显著的抑制作用；在保肝试验中，给药组能明显抑制ast的升高，对肝损伤有一定的保护作用。

Treatment under mild condition with solvent of lower polarity was in favor of keeping the molecular structure and properties such as water-solubility, gelatination, etc. Acetyl groups were partially eliminated when purified by Pb2 method, leading to increased crystallinity and glass temperature, which resulted in losts of water-solubility and gelatinability. Owing to the slight oxidative degradation with H2O2 method, the changes of chain size and some functional groups of KGM molecule led to decrease of viscosity and excessive swelling rate.

采用温和条件及低极性溶剂有利於保持KGM本身的分子结构以及水溶性、凝胶性等性能；而Pb2法由於部分脱去了KGM的乙酰基，导致结晶度变大，玻璃化温度升高，最终失去水溶性和凝胶性；H2O2法则由於对KGM造成了氧化降解，也改变了分子链的大小以及部分基团，从而导致粘度降低以及溶涨速度较快。
