Tian, Wenni published the artcileStructure, antioxidant and immunomodulatory activity of a polysaccharide extracted from Sacha inchi seeds, Recommanded Product: (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is Plukenetia seed polysaccharide antioxidant immunomodulatory activity; Immunostimulatory activity; Plukenetia volubilis L. seed; Polysaccharides structure.
In this study, a novel water-soluble polysaccharide (PVLP-1) was extracted and purified from Sacha inchi (Plukenetia volubilis L.) seeds and the structure, antioxidant and immunomodulatory activity of PVLP-1 were investigated. PVLP-1 (144 kDa) consisted of glucose (69.76%), mannose (14.86%), arabinose (10.53%), galactose (2.42%), ribose (1.23%), rhamnose (0.27%) and xylose (0.93%). PVLP-1 displayed characteristic polysaccharide bands in Fourier transform NMR spectra and IR. The primary structure of PVLP-1 was a heteropolysaccharide with a backbone of (1 â?6)-linked glucose, sidechains of (1 â?4)-linked mannose, (1 â?4)-linked glucose and (1 â?3, 6)-linked mannose and a residue unit of â?)-linked arabinose as revealed the methylation anal. PVLP-1 possessed good water-holding capacity (WHC), oil-holding capacity (OHC) and antioxidant capacities. Besides, PVLP-1 induced the proliferation of RAW264.7 cell and enhanced the expression of inflammatory cytokines IL-6, TNF-alpha(TNF-α) and IL-1 beta (IL-1β). The present study indicated that PVLP-1 possessed immune-enhancing bioactivities and could be functional food or adjuvant drug to improve biol. immunity of immunodeficiency diseases and hypoimmunity.
