| titleOfInvention | The extracting method of polysaccharide and its application in a kind of acute turpinia leaf |
| abstract | The present invention relates to a kind of extracting methods of polysaccharide in acute turpinia leaf, include the following steps：1) ethyl alcohol for being 90~95% with volumetric concentration carries out refluxing extraction to acute turpinia leaf powder, collects residue；2) under the action of ultrasonic wave, the aqueous solution of the residue is digested, supernatant is taken after centrifugation；3) a concentration of the 75~85% of wherein absolute ethyl alcohol after the supernatant concentration to 0.5~1g/ml of crude drug amount, will be adjusted, is centrifuged after stand at low temperature, collects precipitation；4) de- albumen processing is carried out to the precipitation with sevage solwution methods, obtains Deproteinated polysaccharide solution；5) a concentration of 75~85% of absolute ethyl alcohol in the Deproteinated polysaccharide solution are adjusted again, are centrifuged after stand at low temperature, collect precipitation, acute turpinia leaf polysaccharide is obtained after dry.The present invention realizes the maximization of polysaccharide extract rate；And present invention process is simple, and it is green, nontoxic and environmentally friendly, it is suitable for industrialization promotion. |
