The anti-cancer effects of selenylated plant polysaccharides are a focus of research. As a natural plant with extensive biological effects, there have been few studies related to edible purslane ( L.).

In this study, the soluble yam mucilage polysaccharides (YPS) were prepared and selenylated in the HNO-NaSeO system, and two selenylated polysaccharide products, namely SeYPS-1 and SeYPS-2 with respective Se contents of 719 and 1585 mg/kg, were thus obtained. GC-MS analysis demonstrated that the compositional features of SeYPS-1 and SeYPS-2 were similar to those of YPS.

The obtained PSPO were selenylated using the NaSeO-HNO method to successfully prepare two selenylated products, namely SePSPO-1 and SePSPO-2, with different selenylation extents.

In this study, the YPS was selenylated with NaSeO under acidic conditions generated by HNO to reach two lower selenylation extents, yielding two selenylated YPSs, namely SeYPS-1 and SeYPS-2 with selenium contents of 715 and 1545 mg/kg, respectively. The results indicated that YPS, SeYPS-1, and SeYPS-2 all had in vitro immuno-modulation when using RAW 264.
