Study on extraction and ability to scavenge hydroxyl radicals for Polysaccharides from Portulaca oleracea L.───马齿苋粗多糖的提取及清除羟自由基活性作用。
Portulaca oleracea is a kind of wild vegetable having various nutritions and health functions.
MethodsThe polysaccharides of Portulaca oleracea were obtained through hot water extraction and ethanol precipitation, which content was determined by phenol-vitriolic colorimetry.
Results The Portulaca oleracea L. contained many kinds of chemical constituents, primarily including organic acids, flavonoids, terpenoids, coumarins, alkaloids.
Results:Portulaca extracts improved the devouring percentage and index of macrophage cell and promoted the formation of hemolysin and hemolysis void the transformation of lymphocyte.
Conclusion The stems and the roots of Portulaca oleracea L have a strong effect of anti-oxygen free radical in vitro and in vivo, while its leaves has the effect only in vitro.
Objective: To identify anti-hypoxia ingredients extracted from Portulaca oleracea and to find out the possible mechanism of its anti-hypoxia actions.
Conclusion: Portulaca extracts can improve the immunitive function.
The functional character and exploitation of Portulaca oleracea L.
CONCLUSION: Ethanol extract from Portulaca oleracea L. can obviously increase the ability of hypoxia tolerance of mice.
