Embodiment 1

[0027] A method for quickly identifying the authenticity of Cordyceps mycelium is characterized by comprising the following steps:

[0028] (1) Compression and scanning of potassium bromide blank tablets: Accurately weigh 200 mg of dry potassium bromide fine powder; place it in an agate mortar and grind it thoroughly, and transfer the potassium bromide fine powder to a compactor with a diameter of 13 mm. In the film, spread evenly, pressurize to 0.8Gpa, and keep it for 1min. The potassium bromide blank sheet made by visual inspection is uniform and transparent, without obvious particles; put the pressed potassium bromide blank sheet into Fourier transform infrared Background scanning is carried out in the scanning chamber of the spectrometer to obtain the standard sample spectrum ( figure 1 );

[0029] (2) Sample tableting and scanning: accurately weigh 3 mg of Cordyceps mycelia medicinal material that has been crushed through an 80-mesh sieve, and precisely weigh 200 mg of d...

Embodiment 2

[0032] A method for quickly identifying the authenticity of Cordyceps mycelium is characterized by comprising the following steps:

[0033] (1) Compression and scanning of potassium bromide blank tablets: Accurately weigh 200 mg of dry potassium bromide fine powder; place it in an agate mortar and grind it thoroughly, and transfer the potassium bromide fine powder to a compactor with a diameter of 13 mm. In the film, spread evenly, pressurize to 0.8Gpa, and keep it for 1min. The potassium bromide blank sheet made by visual inspection is uniform and transparent, without obvious particles; put the pressed potassium bromide blank sheet into Fourier transform infrared Background scanning is performed in the scanning room of the spectrometer to obtain the standard sample spectrum;

[0034] (2) Sample tableting and scanning: accurately weigh 3 mg of Cordyceps mycelia medicinal material that has been crushed through an 80-mesh sieve, and precisely weigh 200 mg of dried potassium brom...

Abstract

The invention discloses a method for quickly identifying true and false cordyceps mycelia. The method comprises the following steps of: (1) tabletting and scanning a potassium bromide blank film to obtain a standard sample spectrum; (2) tabletting and scanning a sample, namely accurately weighing the cordyceps mycelium which is crushed and screened via a 80-meshe sieve and fine potassium bromide powder, grinding and uniformly mixing the two powder, uniformly laying the mixed powder in a pressure membrane, and pressurizing the mixed powder for 1 min so as to obtain a sample sheet, and carrying out Sample scanning on the pressed sample sheet into a fourier infrared spectrometer scanning chamber, thus obtaining a cordyceps mycelium sample spectrum; and (3) comparing the similarity of the cordyceps mycelium sample spectrum and a standard sample spectrum, wherein the criterion is that the similarity of the cordyceps mycelia is higher than 0.95. The method disclosed by the invention can be used for quickly identifying the true and false cordyceps mycelia on the basis of the difference of spectral absorption of the cordyceps mycelium; the detection is fast, samples are not damaged, and the use quantity of the cordyceps mycelia is little; and the samples are subjected to full wave infrared spectrum scanning, so that the information of the samples is complete.

Description

technical field [0001] The invention relates to a method for rapidly identifying the authenticity of the mycelium of Cordyceps sinensis. Background technique [0002] Cordyceps mycelium is a product obtained by extracting effective strains from natural Cordyceps sinensis using bio-separation technology, and then inoculating and cultivating them in a large-volume liquid medium to make Cordyceps mycelia grow in large quantities (fermentation). [0003] The Cordyceps mycelium obtained through fermentation and the natural Cordyceps have been strictly tested. They have no difference in function and efficacy, but the production cost is greatly reduced. Cordyceps mycelium is an effective substitute of Cordyceps sinensis, it has the same function as Cordyceps sinensis: enter the lung, liver, kidney meridian, has the effects of nourishing the lung, kidney, strengthening the liver, replenishing qi, nourishing essence, no toxic side effects, can Improving the immune function of the hu...
