Embodiment 1

[0011] A preparation method of Cordyceps mycelium extract, comprising the following steps:

[0012] Dry the Cordyceps mycelium in an oven at 55°C for 10 hours in a vacuum with a vacuum degree of 0.05 MPa. After drying, pulverize and sieve through 20 meshes to make a coarse powder; add the coarse powder to a multi-functional extraction tank and add a solvent , heated to 80°C, refluxed for 2 hours, cooled to room temperature, filtered, the filtrate recovered solvent, dried in an oven at 80°C, and made into a dry paste, that is, Cordyceps mycelium extract .

Embodiment 2

[0014] A preparation method of Cordyceps mycelium extract, comprising the following steps:

[0015] Dry the Cordyceps mycelium in an oven at 60°C for 8 hours in a vacuum with a vacuum degree of 0.01MPa. After drying, pulverize and sieve through 20 meshes to make a coarse powder; add the coarse powder to a multi-functional extraction tank and add solvent , heated to 60°C, refluxed for 1.5°C, cooled to room temperature, filtered, the filtrate recovered solvent, dried in an oven at 80°C, and made into a dry paste, that is, Cordyceps mycelium extract .

Embodiment 3

[0017] A preparation method of Cordyceps mycelium extract, comprising the following steps:

[0018] Dry the Cordyceps mycelium in an oven at 58°C for 9 hours in vacuum with a vacuum degree of 0.02MPa. After drying, crush and sieve through 20 meshes to make a coarse powder; add the coarse powder to a multi-functional extraction tank and add a solvent , heated to 70°C, refluxed for 1.8h, cooled to room temperature, filtered, the filtrate recovered solvent, dried in an oven at 80°C, and made into a dry paste, that is, Cordyceps mycelium extract .

Abstract

The invention relates to a preparation method of a cordyceps sinensis mycelium extract. The preparation method is characterized by comprising the following steps of: putting the cordyceps sinensis mycelium in an oven, and performing vacuum drying at 55-60 DEG C for 8-10 hours, wherein the vacuum degree is 0.01-0.05MPa; after the drying, crushing and screening by a 20-mesh sieve to obtain coarse powder; adding the coarse powder into a multifunctional extraction tank, and adding a solvent; heating to 60-80 DEG C, and refluxing for 1.5-2 hours; cooling to normal temperature, and filtering; recovering the solvent from the filtrate; and drying in the oven at 80 DEG C to obtain a dry paste which is the cordyceps sinensis mycelium extract. The solvent comprises the following components in parts by mass: ethyl alcohol, ethyl acetate, petroleum ether and tributylamine at a mass ratio of (60-85):(5-25):(5-25):(5-10). By adopting the method provided by the invention, the prepared cordyceps sinensis mycelium extract can be added into a Chinese medicine preparation according to the prescription percentage to prepare a preparation; and the pharmacological components of the cordyceps sinensis mycelium are uniformly dispersed and quickly dissolved out in the body to last for long time and promote sufficient absorption by the human body.

Description

Technical field [0001] The present invention is the field of traditional Chinese medicine extraction, and it is specifically involved in the preparation method of a Cordyceps sibacterius obtsengers. Background technique [0002] Cordyceps sinensis (referred to as Cordyceps) is a traditional precious Chinese medicinal material. In recent years, with the ecological destruction, resources have become increasingly exhausted.People artificial cultivation of the mycelium or sub -entities collected by wild Cordyceps sinensis to form a larger industrial scale and make up for the lack of natural growth of Cordyceps resources.Even so, Cordyceps and mycelium prices are still expensive, which restricts people in in -depth research.In addition, the artificial cultivation of Cordyceps sago and wild cordyceps components are complicated, and they all contain such as amino acids, D-glycol, twentanane, nucleoside, and picanol and polysaccharides.The above ingredients have a very good effect on the...
