Embodiment 1

[0019] A method for extracting Cordyceps sinensis extract, comprising the following steps:

[0020] S1, washing Cordyceps sinensis, removing impurities, drying in the air, then drying at 30°C, crushing to 20-35 meshes to obtain Cordyceps sinensis micropowder;

[0021] S2. Add Cordyceps micropowder into the hydrochloric acid solution with a pH value of 5, heat up to 35°C and sonicate for 3 minutes, adjust the pH of the system to 7 and then sonicate for 10 minutes, adjust the pH of the system to 8 and then sonicate for 10 minutes, and heat up to 60°C , adding ethanol so that the volume of ethanol is 45% of the total volume of the system, ultrasonication for 10 min, then microwave at 50°C for 50 s, and filter to obtain the extract;

[0022] S3. Concentrating the extract under reduced pressure to a solid content of 85% to obtain the Cordyceps sinensis extract.

Embodiment 2

[0024] A method for extracting Cordyceps sinensis extract, comprising the following steps:

[0025] S1, washing Cordyceps sinensis, removing impurities, drying in the air, then drying at 35°C, crushing to 20-35 meshes to obtain Cordyceps sinensis micropowder;

[0026] S2. Add the micropowder of Cordyceps sinensis into the nitric acid solution with a pH value of 3, heat up to 38°C and sonicate for 8 minutes, adjust the pH of the system to 7 and then sonicate for 6 minutes, adjust the pH of the system to 10 and then sonicate for 7 minutes, heat up to 67°C , adding ethanol so that the volume of ethanol is 38% of the total volume of the system, ultrasonication for 22min, then microwave at 46°C for 66s, and filter to obtain the extract;

[0027] S3. Concentrating the extract under reduced pressure to a solid content of 89% to obtain the Cordyceps sinensis extract.

Embodiment 3

[0029] A method for extracting Cordyceps sinensis extract, comprising the following steps:

[0030] S1, washing Cordyceps sinensis, removing impurities, drying in the air, then drying at 42°C, crushing to 20-35 meshes to obtain Cordyceps sinensis micropowder;

[0031] S2. Add the micropowder of Cordyceps sinensis into the mixture of phosphoric acid solution and oxalic acid solution with a pH value of 4, heat up to 42°C and sonicate for 5 minutes, adjust the pH of the system to 7 and then sonicate for 8 minutes, and use triethylamine to adjust the pH of the system. After 9, sonicate for 8 minutes, heat up to 63°C, add ethanol so that the volume of ethanol is 42% of the total volume of the system, sonicate for 16 minutes, then microwave at 48°C for 58s, and obtain the extract after filtration; wherein, in the process of ultrasonic , the ultrasonic power is 900W;

[0032] S3. Concentrating the extract under reduced pressure to a solid content of 92% to obtain the Cordyceps sinen...

Abstract

The invention discloses a method for extracting a cordyceps sinensis extract. The method comprises the following steps: 1, preparing cordyceps sinensis micro-powder; 2, adding the cordyceps sinensis micro-powder into an acid solution, heating, performing ultrasonic treatment, adjusting the pH value of the system, and filtering, thereby obtaining an extraction liquid; and 3, performing depressurized concentration on the extraction liquid, thereby obtaining the cordyceps sinensis extract. The method for extracting the cordyceps sinensis extract is simple in process, gentle in condition and high in extract content.

Description

technical field [0001] The invention relates to the technical field of Cordyceps sinensis, in particular to a method for extracting Cordyceps sinensis extract. Background technique [0002] Cordyceps sinensis has a variety of active ingredients, such as cordycepic acid, cordycepin and adenosine, etc., so that Cordyceps sinensis has various pharmacological effects such as sedation, antibacterial, inhibition of mouse ascites cancer, and enhancement of immune function. At present, there are many extraction techniques for active components in Cordyceps sinensis at home and abroad, but they have the defect of low extraction rate, which increases the cost of extraction. Contents of the invention [0003] The purpose of the present invention is to solve the shortcoming existing in the prior art, and propose a kind of extraction method of Cordyceps sinensis extract, and its process is simple, and condition is mild, and extraction rate is high. [0004] In order to achieve the abo...
