| titleOfInvention | Sedum sarmentosum homogeneous polysaccharide and preparation method and application thereof |
| abstract | The invention discloses a sedum sarmentosum homogeneous polysaccharide and a preparation method and application thereof. The herba Sedi homogeneous polysaccharide has total sugar content of above 99%, and molecular weight of 1-30 kDa. A method for preparing stringy stonecrop herb homopolysaccharide comprises the following steps: taking the whole dry sedum sarmentosum, degreasing, extracting, precipitating and drying to obtain a crude sedum sarmentosum polysaccharide product; dissolving the obtained crude product of the sedum sarmentosum polysaccharide by using distilled water, loading the solution into an anionic cellulose chromatographic column, and eluting by using the distilled water to obtain sedum sarmentosum water-washing component polysaccharide; purifying the obtained water-washing component polysaccharide by using a gel chromatographic column, and eluting by using a NaCl solution to obtain the uniform sedum sarmentosum polysaccharide. The application of herba Sedi homogeneous polysaccharide in preparing antitumor drugs is provided. The invention extracts and separates the stringy stonecrop herb homogeneous polysaccharide from the stringy stonecrop herb for the first time, and has the function of preventing and treating the tumor of patients with low anti-tumor function. The preparation method is simple, can quickly obtain high-purity uniform polysaccharide, and is suitable for large-scale production. |
