| titleOfInvention | Amomum villosum polysaccharide with immunoregulation effect and preparation method and application thereof |
| abstract | The invention discloses amomum villosum polysaccharide with an immunoregulation effect and a preparation method and application thereof. The invention separates the great molecular weight acidic polysaccharide AVPG-2 of the amomum villosum for the first time, and the great molecular weight acidic polysaccharide AVPG-2 is measured by a high-efficiency size exclusion chromatography and multi-angle laser light scattering instrument combined differential detector (HPSEC-MALLS-RID), and the weight average molecular weight is 1.48 multiplied by 10 7 Da, analyzed by HPLC, the polysaccharide AVPG-2 of amomum villosum is mainly composed of rhamnose, glucuronic acid,Galacturonic acid, glucose, galactose, xylose and arabinose. According to Congo red analysis, the structure has a triple helix structure. AVPG-2 can remarkably promote macrophage RAW 264.7 to generate NO and secrete cell factors IL-6 and TNF- α And the cell activity and phagocytic capacity of macrophage RAW 264.7 are improved, and the preparation method is expected to be used for preparing immunoregulation health-care products or medicines. |
