Glycopeptide extract from ganoderma spore powder, method for preparing glycopeptide extract and application thereof

The invention belongs to the field of traditional Chinese medicines, and relates to glycopeptide extract from ganoderma spore powder, a method for extracting the glycopeptide extract and application thereof. The method sequentially includes steps of extracting the ganoderma spore powder by the aid of concentrated alcohol; extracting the ganoderma spore powder by the aid of diluted alcohol; combining concentrated-alcohol extract liquid and diluted-alcohol extract liquid with each other to obtain mixed extract liquid and degreasing the mixed extract liquid by the aid of diethyl ether; removing impurities from the mixed extract liquid and decolorizing the mixed extract liquid; purifying the mixed extract liquid by the aid of resin. The method preferably further includes steps of further treating ganoderma spore powder residues by the aid of aqueous extraction, alcohol precipitation and refining steps. The ganoderma spore powder residues remain after the ganoderma spore powder is extracted by the aid of the concentrated alcohol and the diluted alcohol. The glycopeptide extract is prepared by the aid of the method. The glycopeptide extract, the method and the application have the advantages that the method for extracting the glycopeptide extract from the ganoderma spore powder is easy and convenient to implement and low in cost and is environmentally friendly and safe, good extraction effects can be realized, structures of the glycopeptide extract can be prevented from being destroyed, solvents can be recycled, and industrial production can be facilitated; excellent effects can be realized by the glycopeptide extract when the glycopeptide extract is used for increasing leukocytes.
