Purification, characterization and immunomodulating activity of a pectic polysaccharide isolated from Korean mulberry fruit Oddi (Morus alba L.)



Purification, characterization and immunomodulating activity of a pectic polysaccharide isolated from Korean mulberry fruit Oddi (Morus alba L.)



International Immunopharmacology 17(3): 858-866



A water-soluble polysaccharide (JS-MP-1) was isolated and purified from the Korean mulberry fruits Oddi (Morus alba L.) by crushing the fresh fruits then performing ethanol precipitation and DEAE-cellulose ion exchange chromatography. The neutral monosaccharide composition of the purified JS-MP-1 was determined to be composed mainly of galactose (37.6%, in mole percent), arabinose (36.3%), and rhamnose (18.4%), while other major sugars such as glucose, xylose, mannose, and fucose were present as minor components. HPLC analysis revealed that JS-MP-1 contains both galacturonic acid (GalA) and glucuronic acid (GlcA) at approximately 4:1 in mole percent. Monosaccharide composition, Fourier-transform infrared (FTIR) analysis, biochemical analysis, and elemental analysis suggested that JS-MP-1 is an acidic heteropolysaccharide, most likely a rhamnoarabinogalacturonan type plant pectic polysaccharide, with an apparent molecular mass of 1600 kDa containing no, or if any, negligible level of sulfate esters and proteins. Enzyme-Linked Immunosorbent Assay and RT-PCR analysis demonstrated that JS-MP-1 significantly stimulates murine RAW264.7 macrophage cells to release chemokines (RANTES and MIP-1α) and proinflammatory cytokines (TNF-α and IL-6) and to induce the expression of iNOS and COX-2, which are responsible for the production of NO and prostaglandin PGE2, respectively. These results suggest that the mulberry fruit-derived polysaccharide JS-MP-1 can act as a potent immunomodulator, and these observations may support the applicability of this polysaccharide as an immunotherapeutic adjuvant or the water extracts of the mulberry fruit as a beneficial health food.
