Problems solved by technology

Another example is bitter almonds. Its active ingredient is amygdalin. After entering the intestinal tract, amygdalin is decomposed into hydrocyanic acid by intestinal bacteria to play a calming and antitussive effect. After harvesting, leave it for a long time to enzymatically decompose amygdalin into hydrocyanic acid and lose it by volatilization, reducing the quality of bitter almonds

Embodiment 1

[0063] A method for drying Scutellaria baicalensis medicinal material, comprising the steps of:

[0064] (1) Clean selection: remove impurities such as sediment and stones, remove non-medicated parts and moth and mildew parts;

[0065] (2) Purify the medicine: clean the fresh medicinal materials, remove the soil and floating dust on the surface of the medicinal materials;

[0066] (3) Pre-freezing: Put the medicinal materials into the freezer to freeze, the freezing temperature is -10℃~-18℃, and the freezing time is 1-5h;

[0067] (4) Vacuum drying: take out the frozen medicinal materials from the freezer, and dry them in a vacuum environment for 2 hours;

[0068] (5) Microwave drying: Lay the medicinal materials in a microwave at 600W power for 30s. The thickness of the medicinal materials does not exceed 2cm. Take out the medicinal materials and turn them, then put them in the microwave power of 800W and dry them for 30s. Dry for 20s under the condition of microwave power ...

Embodiment 2

[0075] A drying method for Polygonatum medicinal material, comprising the steps of:

[0076] (1) Clean selection: remove impurities such as sediment and stones, remove non-medicated parts and moth and mildew parts;

[0077] (2) Purify the medicine: clean the fresh medicinal materials, remove the soil and floating dust on the surface of the medicinal materials;

[0078] (3) Moisturizing: pile the medicinal materials on the medicinal table, cover them with damp cloth, wet sacks and other wet objects, and spray appropriate amount of water from time to time to keep them moist, so that the moisture from the outside of the medicinal materials can slowly penetrate into the tissue to achieve the same internal and external humidity. easy to cut;

Abstract

The invention relates to the technical field of treatment of traditional Chinese medicine, in particular to a method for drying traditional Chinese medicinal herbs. The method mainly includes the steps of 1), selecting, namely removing impurities of sediment, stones and the like and removing non-medicine parts and moth mildew parts; 2), cleaning, namely cleaning up fresh medicinal herbs and removing dirt and dust on surfaces of the medicinal herbs; 3), pre-freezing, namely putting the medicinal herbs into a freezer for freezing, wherein the freezing temperature is minus 10-minus 18 DEG C, andfreezing time is 1-5 hours; 4), vacuum drying, namely taking out the frozen medicinal herbs from the freezer and placing the same into a vacuum environment for drying; 5), packaging, namely packagingthe dried medicinal herbs. The medicinal herbs are frozen at the low temperatures, moisture in the medicine herbs is turned into icy water, the medicine herbs are directly sublimed and dehydrated in vacuum, enzyme activity is quite low at the low temperatures, and resolving of glycoside active ingredients is inhibited; in addition, cell walls are favorably broken at the low temperatures, and dissolution of effect ingredients is facilitated in subsequent decocting of the medicinal herbs.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine treatment, in particular to a drying method for Chinese medicinal materials. Background technique [0002] Traditional Chinese medicine comes from plants, animals, minerals and their processed products in nature. Its chemical composition is very complex. Glycosides are one of the active ingredients widely present in many traditional Chinese medicines. Glycosides are formed by linking non-sugar aglycone and sugar or sugar derivatives through the terminal carbon atoms of the sugar. Most of them are soluble in polar solvents such as water and wine, and can also be hydrolyzed by acid, alkali and enzymes. [0003] The glycosides contained in plants often exist in different cells of the same tissue at the same time as the enzymes that hydrolyze them. When the plant tissue is damaged, under a certain temperature and humidity, the enzymes will hydrolyze the glycosides into aglycones a...
