Problems solved by technology

[0003] However, in wild Cordyceps, the content of cordycepin is low, which greatly restricts its nutritional value, and the content of cordycepin in the existing artificially cultivated Cordyceps has not been greatly improved

Embodiment Construction

[0010] A Cordyceps militaris culture medium is used for cultivating Cordyceps militaris. The dry base of the Cordyceps militaris culture medium includes the following components in terms of mass percentage: 70% of silkworm chrysalis, 10% of tartary buckwheat, 7% of quinoa, 5% of Moringa oleifera leaves, and yeast powder 5%, acetic acid 2%, glucose 1%. After the dry base is prepared, add water and stir evenly with the dry base. The mass ratio of the dry base to water is 5:3. The mixing time of dry base and water is 20-25 minutes.

[0011] The following table shows the comparison (mg / 100g) of the contents of cordycepin and adenosine in Cordyceps militaris grown on the Cordyceps militaris medium of the present invention and the existing Cordyceps militaris.

[0012] Cordyceps militaris cultivated by the present invention Existing Cordyceps Cordycepin content 1030.1 12.3 Adenosine content 147.4 1.5

[0013] As can be seen from the above table, in t...

Abstract

The invention discloses a cordyceps militaris culture medium, which is used for culturing cordyceps militaris. The cordyceps militaris culture medium is prepared from the following components in percentage by mass on the dry basis: 70% of silkworm chrysalis, 10% of tartary buckwheat, 7% of quinoa, 5% of horseradish tree leaf, 5% of yeast powder, 2% of acetic acid, and 1% of glucose. The cordyceps militaris culture medium has the advantages that the determined components after multiple times of test are prepared into the cordyceps militaris culture medium; the content of cordycepin in the cordyceps militaris cultured by the cordyceps militaris culture medium is greatly increased.

Description

technical field [0001] The invention relates to the field of Cordyceps cultivation, in particular to a culture medium of Cordyceps militaris. Background technique [0002] Cordyceps militaris is a combination of insects and bacteria artificially cultivated by inoculating the spores of wild natural pupae strains on silkworm pupae. Cordycepin is the main active ingredient in Cordyceps sinensis, and it is also the first nucleoside antibiotic isolated from fungi. It is a natural source of medicine, which has the same yin and yang tonic and two-way regulation of human body balance as Cordyceps sinensis in traditional Chinese medicine. Function: it is more effective in protecting the liver, protecting the kidney, and nourishing the lungs because of its purer ingredients, and it can nourish qi and blood, and can eliminate diseases such as dysmenorrhea, migraine, and cervical hyperplasia that cannot be cured now. [0003] However, in wild Cordyceps, the content of cordycepin is low...
