In Vitro Immuno-Modulatory Potentials of Purslane (Portulaca oleracea L.) Polysaccharides with a Chemical Selenylation
The soluble polysaccharides from a non-conventional and edible plant purslane (Portulaca oleracea L.), namely PSPO, were prepared by the water extraction and ethanol precipitation methods in this study.The obtained PSPO were selenylated using the Na2SeO3-HNO3 method to successfully prepare two selenylated products, namely SePSPO-1 and SePSPO-2, wit
