Characteristics and immunomodulation of macrophages of two polysaccharides of Péonia Andrea suffruticose. PSAP-1 and PSAP-2 have been studied in this study, cleaned by anion-exchange chromatography followed by size exclusion chromatography. The results indicate that both PSAP-1 and PSAP-2 have a strong immunostimulating effect and can be considered as potential natural immunomodulating agents in medicine or functional nutrition. The results showed that PSAP-1 with a molecular weight of 155 kDa consists mainly of glucuronic acid, glucose, Arabinose and galactose with molar content of 0.83, 11.53, 18.83, 11.53 and 18.13, 8.35, 12.20, 14.75 and 55.57%, respectively, PSAP-2 showed higher immunomodulatory activity than PSAP-1. In providing this information, we did not diagnose, treat, treat, treat, soften, or prevent any disease or medical condition. More than 500 pages of alternatives and information on natural medicine. It is recommended that you consult an authorized physician before performing any natural, integrative, or routine treatment. Andr. Paeongya Sufruticoza has a long cultural history in China, and the flower has great nutritional and therapeutic value.
