| 摘 要： | 采用超声波法从仙人掌中提取多糖,并对仙人掌多糖进行硫酸酯化处理。通过单因素、正交实验对比研究仙人掌多糖硫酸酯化前后对自由基的清除作用。结果表明:仙人掌多糖硫酸酯化前后对.OH均有一定的清除作用,且均随浓度升高清除能力不断增强,但仙人掌硫酸酯化多糖对.OH的清除能力较低。

| Abstract: | The polysaccharide of Cactus was extracted with ultrasonic waves. Further on the Cactus for sulfated polysaccharide treatment. Free radical scavenging qualities of polysaccharide from cactus and its sulfated derivative were comparatived by the methods of single factorand orthogonal design test. The results make sure that the cactus polysaccharideand sulfated polysaccharide have certaineffect on scavenging the free radicals. The scavenging ratio to OH is increased by a certain trend with the increasing the concentration of polysaccharide of cactus, But sulfated polysaccharide is less potent than polysaccharide at scavenging .OH. |
