| titleOfInvention | A kind of geranium neutral polysaccharide and its preparation method and application |
| abstract | The invention discloses a geranium neutral polysaccharide and its preparation method and application. The geranium neutral polysaccharide is composed of L-rhamnose, D-arabinose and D-mannose residue links, and L- The rhamnose:D‑arabinose:D‑mannose molar ratio is 7.59:1:0.15 and the molecular weight is 1663 Da. The preparation method is to extract the geranium crude polysaccharide by using a composite extraction method of water extraction and alcohol precipitation, which is not only simple in operation and low in cost, but also more efficient and practical, and the biological activity of the polysaccharide is also better guaranteed. The neutral polysaccharide extracted from Geranium in the present invention has anti-inflammatory and antioxidant activities, and it has initially inhibited the secretion level of TNF-α and IL-6 at a concentration of 10 μg/mg. At 0.8 mg/mL, it already has a certain DPPH free radical scavenging ability, and has the characteristics of less toxic and side effects. It has broad application prospects in the development of low-toxicity and high-efficiency anti-inflammatory and antioxidant drugs, which is beneficial to the development of geranium Further development and utilization of resources. |
