Abstract

The invention relates to a method for increasing the content of cordycepin in cordyceps militaris sporocarp. It is required that high-temperature stress treatment is adopted in the particular period of culture of the cordyceps militaris sporocarp, namely from the 40th day to the 50th day, the culture temperature is raised to 24-30 DEG C from 15-20 DEG C to be kept for 10-20 days, harvesting is conducted on the day ranging from the 55th day to the 65th day, and the cordyceps militaris sporocarp with the cordycepin content reaching 0.5% can be obtained. According to the method, from the 40th-50th day of cordyceps militaris sporocarp culture, high-temperature stress treatment is adopted; meanwhile, strong white light or strong blue light stimulation treatment is assisted, and the content of the cordycepin in the cordyceps militaris sporocarp can be further increased and can reach 0.6%-0.9% and 0.9%-1.5%. The method has great innovativeness and application value.

Description

technical field [0001] The invention relates to the technical field of artificial cultivation of Cordyceps militaris, in particular to an artificial cultivation method for increasing the content of cordycepin in fruit bodies of Cordyceps militaris. Background technique [0002] Cordyceps militaris ( Cordyceps militaris (L.)Link ) belongs to Eumycota, Ascomycota, Ascomycotinia, Sordariomycetes, Hypocreomycetidae, Hypocreales, Cordyceps family (Cordycipitaceae), Cordyceps ( Cordyceps ). Cordyceps militaris, also known as Cordyceps militaris, has similar bioactive components to Cordyceps sinensis, mainly including cordycepin, cordycepic acid, polysaccharides, ergosterol, amino acids, nucleosides, etc. Its efficacy is similar to that of Cordyceps sinensis, and it is a good substitute for Cordyceps sinensis. And the content of cordycepin is also higher than that of Cordyceps sinensis. [0003] Cordycepin (3′-deoxyadenosine), also known as cordycepin, is the first nucleoside ...
