Problems solved by technology

At present, most of the high-pressure extraction technologies for plants are extracted under high temperature and high pressure, or soak the plants in the extraction solvent at room temperature and then perform high-pressure extraction. The high-pressure device is not easy to clean, takes a long time, consumes a lot of energy, and has low production efficiency. shortcoming
[0005] At present, there is no relevant report on the extraction of plant natural active ingredients by cold explosion technology.

Embodiment 1

[0023] Cut ginseng into 5mm strips and put them into a high-pressure tank, fill the high-pressure tank with air at 15°C until the pressure in the high-pressure tank reaches 10 MPa and keep the pressure for 15 minutes, then release the pressure of the high-pressure tank to normal within 0.1s Press the ginseng material in the tank to cause cold explosion, collect the ginseng material after the cold explosion, add methanol with a volume fraction of 90% according to the material ratio of 1:28, soak for 10min and stir at 15°C, and control the stirring speed to 50rpm. Then filter, take the filtrate, evaporate the methanol in the filtrate at 35°C, control the evaporation time to 60min, and the remaining solid product is the natural active ingredient of ginseng; collect the evaporated methanol, and reuse it after purification.

Embodiment 2

[0025] Cut platycodon root into 12mm strips and put it into a high-pressure tank. Fill the high-pressure tank with nitrogen at 18°C ​​until the pressure in the high-pressure tank reaches 15 MPa and keep the pressure for 12 minutes, then release the pressure of the high-pressure tank to normal within 0.3s. Press down, make the bellflower material in the tank cold burst, collect the bellflower material after the cold explosion, add volume fraction by the material ratio of 1:100 is 55% methanol, soak 9min and stir at 18 ℃, the control stirring speed is 50rpm, Then filter, take the filtrate, evaporate the methanol in the filtrate at 37°C, control the evaporation time to 140min, and the remaining solid product is the natural active ingredient of Platycodon grandiflora; collect the evaporated methanol, purify and reuse.

Embodiment 3

[0027] Cut Epimedium into 20mm strips and put them into a high-pressure tank, fill the high-pressure tank with carbon dioxide at 22°C until the pressure in the high-pressure tank reaches 20 MPa and keep the pressure for 10 minutes, then release the pressure in the high-pressure tank within 0.3s To normal pressure, the Epimedium material in the tank is cold-exploded, and the Epimedium material after the cold-explosion is collected, and the volume fraction is 95% ethanol added at a material ratio of 1:50, soaked at 20°C for 7min and stirred, Control the stirring speed to 40rpm, then filter, take the filtrate, evaporate the ethanol in the filtrate at 39°C, control the evaporation time to 200min, the remaining solid product is the natural active ingredient of Epimedium; collect the evaporated ethanol, and reuse it after purification.

Abstract

The invention discloses a method for extracting natural active ingredients from plants by through a cold explosion technology. The method comprises crushing plants, putting the crushed plants into a high pressure tank, increasing pressure in the high pressure tank to 10-35MPa at 15-30 DEG C, keeping the pressure for 2-15min, releasing the pressure in the high pressure tank to the normal pressure in 0.1-0.3s so that the plants in the tank is subjected to cold explosion, collecting the plant materials subjected to cold explosion, adding an extraction solvent into the plant materials, carrying out immersion at 15-25 DEG C, carrying out appropriate stirring, carrying out solid-liquid separation and collecting the liquid as a soluble desired product from plants. The method can evaporate the extraction solvent at a low temperature to acquire solid plant natural active products. The cold explosion technology can damage the surface and inner structure of the plant, fast extracts the natural active ingredients at a low temperature or normal temperature, prevents the damage to the natural active ingredients of the plant because of heat effects, is free of pressure treatment on the extractionsolvent and the plants, has a simple process of cleaning the high pressure tank, has fast extraction time, has a short production period, reduces a production cost and improves the production economic benefits.

Description

technical field [0001] The invention relates to the technical field of extraction of plant natural active ingredients, and more specifically relates to a method for extracting plant natural active ingredients by cold-explosion technology. Background technique [0002] At present, the natural product extraction technology has been widely used in the fields of medicine, food, daily necessities, cosmetics, health products and agricultural products, and the existing natural product extraction technology includes reflux extraction, low temperature impregnation or percolation extraction, supercritical CO 2 Extraction, microwave extraction and ultrasonic extraction, etc. However, the application of the above-mentioned extraction techniques has certain limitations, and the effects are not very satisfactory. [0003] In daily life, people often heat food in a high-pressure container to evaporate the water in the food. Due to the high pressure of the high-pressure container, the wate...
