As patent No. 021021678 discloses " the extracting method of Polygonatum polysaccharide ", extracts and separates Polygonatum polysaccharide by boiling repeatedly with water extraction method, and patent No. CN102351960A discloses " the extraction method of Polygonatum polysaccharide ", and it adopts ultrasonic extraction mode, and the steps involved are relatively It is cumbersome, the extracted Polygonatum polysaccharide is not high in purity and contains more impurities
Generally speaking, the current preparations of Polygonatum polysaccharides all have the following deficiencies: 1. The yield of the obtained polysaccharides is not high, the purity is low, and cannot meet the needs of the market; 2. The extraction process is complicated, time-consuming, high-cost, and difficult for large-scale production; 3. Most of the ion exchange media used for refining polysaccharides are fiber and dextran gel derivatives, which are polysaccharides themselves. When subjected to the action of microorganisms and certain chemical factors, the sugar products are easily polluted by the degradation products of the media
