A Method for Extraction of Polygonatum Sibiricum Polysaccharide Using Deep Eutectic Solvent |
| abstract |
A method of extracting polygonatum sibiricum polysaccharide using deep eutectic solvent belongs to the field of natural product extraction technology. The method 5 includes: Extracting the lyophilized powder of polygonatum sibiricum in a deep eutectic solvent by heating, then separating it by alcohol precipitation, and the precipitate obtained is polygonatum sibiricum polysaccharide. The yield of the extracted polygonatum sibiricum polysaccharide obtained using the low eutectic solvent-ultrasonic assisted method of the present invention is 32.98i2.90%‚ which is 10 about 13 times higher than the extraction yield of polygonatum sibiricum polysaccharide (2.531048%) using the traditional hot water extraction method. |
