| titleOfInvention | Extraction method of cordycepin |
| abstract | The invention discloses an extraction method of cordycepin, which comprises the following steps of: grinding Chinese caterpillar fungus fruit bodies into a powder shape in a planetary ball milling method, wherein the particle size of caterpillar fungus fruit powder reaches about 0.1 mum so that the specific surface area of particles is enlarged, and the cordycepin can be dissolved out; promoting the dissolution of the cordycepin under an appropriate condition by utilizing an ultrasonic dissolving method to improve an extraction rate, and then removing impurities comprising coloring matter, flavonoids compounds, polysaccharide, protein and the like from the cordycepin by using activated carbons and organic solvents to obtain a cordycepin product. Compared with the traditional technology for extracting the cordycepin, by utilizing the extraction method of the cordycepin in the invention, the extraction rate of the cordycepin can be up to over 0.031%, the purity of the cordycepin reaches above 98%, and the extraction method is convenient to operate. Therefore, the extraction method of the cordycepin has the advantages of convenience of operation and high extraction rate and purity of the cordycepin and creates the conditions for the effective utilization of the cordycepin. |
