Two neutral polysaccharides named POP-1 and PCP-1 were purified from Polygonatum odoratum (Mill.) Druce and P. cyrtonema Hua, respectively. The physicochemical and structural characterizations of the polysaccharides were analyzed by the determination of molecular weight, monosaccharide composition, fourier-transform infrared (FT-IR) spectra, NMR spectra. The immunomodulatory activities were evaluated using RAW264.7 macrophage cell line.
