| Abstract: | The content of polysaccharide obtained from Portulaca oleracea was determined by the use of phenol hydrate-sulphuric acid and the optimum extractive technique was tested by orthogonal experiments.Its yield could reach to 9.23%.The polysaccharide was purified,and the physicochemical characteristics of the polysaccharide were studied.On the base of TCL and GC,monosaccharide constituents of this polysaccharide obtained from Portulaca oleracea were analyzed.The result showed that the polysaccharide contained glucose,galactose,mannose,fructose,xylose and arabinose. |
