The homogeneous polysaccharide with an immunoregulatory activity has a single chromatographic peak, the molecular weight of which is 6880 ?50 Da and the optical value of which is 158.4 ?0.5? Infrared spectrometry has an a-configuration saccharide characteristic absorption peak at 847.6 cm-1, the characteristic chemical shift of hydrogen protons in the hydrogen spectrum thereof is 65.40, 63.95, 63.84 and 63.61, and the characteristic chemical shift of carbon signals in a carbon spectrum is 699.6, 676.6, 673.3, 6715, 671.1 and 660.4. The homogeneous polysaccharide has the function of enhancing body immunity, can play a good anti-tumor, anti-virus, anti-infection role, etc. in the regulation of immune-related diseases, and has potential development value in the industry of medicine and healthcare products for treating and preventing diseases. o i!W, 3T#' ya : 6880+50Da, t&f' I 158.4?.5?, 8E B+ tfv flt~iftffi 85.40f3.95, 3.840f3.61, it l th ffrI9676.6, 73.3 71.5, 71.060.4,
