Abstract

The invention discloses an artificial culture method of a zinc-rich cordyceps militaris fruit body and a culture medium thereof. The culture medium comprises the following components by weight portions: 40-65 portions of rice, 0.5-2.0 portions of a yeast extract, 60-85 portions of water and 0.01-1.0 portion of zinc sulfate with the natural PH value. The artificial culture method comprises the following steps: preparation of the culture medium, canning and sterilization; cooling and inoculation; culture; collection of the fruit body; drying and granulation. The method has the advantages of simple operation, short culture period, high yield of the fruit body, no pollution, no waste and zinc supplement function, and the method is suitable for industrialized production.

Description

Technical field: [0001] The invention relates to a method for artificially cultivating fruit bodies of zinc-rich Cordyceps militaris and a culture medium thereof, belonging to the technical field of pharmacognosy. Background technique: [0002] Cordyceps militaris, also known as Cordyceps militaris, belongs to the Ascomycota subphylum Sclerotinia Sclerotiae Sclerotiae Ergotaceae Cordyceps genus, is one of the precious Chinese medicinal materials in my country. Modern pharmaceutical research has shown that Cordyceps militaris contains nucleosides, polysaccharides, cordycepin, sterols and other components, which are basically the same as Cordyceps sinensis. It has therapeutic effects on diseases such as the immune system, nervous system and cardiovascular system, and has anti-tumor and It has anti-cancer effect and is an ideal substitute of Cordyceps sinensis, which has broad development prospects. [0003] Zinc is a kind of trace element, its content and daily intake in the ...
