Embodiment 1

[0020] A method for preserving Chinese medicinal decoction pieces, the method steps are:

[0021] Step 1: Dry the Chinese herbal decoction pieces, stack the Chinese herbal decoction pieces vertically, pack them in cartons, and irradiate them with 60Co-γ rays. The radiation absorbed dose is 1.0 kGy. The carton is rotated around the rotating shaft, and the rotating shaft is perpendicular to the line connecting the center of the irradiation source and the center of the rotating shaft for irradiation treatment. The vertical stacking thickness of the Chinese herbal medicine slices is equal to the thickness of the iso-dose area, and the thickness of the iso-dose area is determined by The distance between the center of the rotating shaft and the center of the radiation source is determined. The farther the distance is, the greater the thickness of the isodose zone will be;

[0022] Step 2: Vacuum-seal the decoction pieces of the traditional Chinese medicine treated in step 1, and per...

Embodiment 2

[0031] A method for preserving Chinese medicinal decoction pieces, the method steps are:

[0032] Step 1: Dry the decoction pieces of the traditional Chinese medicine, stack the decoction pieces of the Chinese medicine vertically, pack them in a carton, and irradiate them with 60Co-γ rays. The radiation absorbed dose is 1.5kGy. The carton is rotated around the rotating shaft, and the rotating shaft is perpendicular to the line connecting the center of the irradiation source and the center of the rotating shaft for irradiation treatment. The vertical stacking thickness of the Chinese herbal medicine slices is equal to the thickness of the iso-dose area, and the thickness of the iso-dose area is determined by The distance between the center of the rotating shaft and the center of the radiation source is determined. The farther the distance is, the greater the thickness of the isodose zone will be;

Abstract

The invention discloses a preservation method of traditional Chinese medicine decoction pieces. The method comprises the following steps: step one, carrying out drying treatment on the traditional Chinese medicine decoction pieces, vertically stacking the traditional Chinese medicine decoction pieces together, packaging with a paper box, and carrying out radiation treatment with 60 Co-gamma rays,wherein the absorbed dose of radiation is 1.0 to 1.5 kGy, a rotating shaft is inserted in the middle part of the paper box in a penetrated manner, and the paper box rotates around the rotating shaft;step two, carrying out vacuum sealing on the traditional Chinese medicine decoction pieces after treatment in the step one, and carrying out secondary radiation treatment, wherein the absorbed dose ofradiation is 2.0 to 2.5 kGy; and step three, putting the traditional Chinese medicine decoction pieces obtained in the step two into a sealed container, inflating a gas mixture of 72% of nitrogen, 25% of carbon dioxide gas and 3% of oxygen into the sealed container, and sealing for storage. According to the method, the uniformity is guaranteed by using mutual compensation of upper and lower surfaces in an equivalent dose area, so that the preservation effect is improved.

Description

technical field [0001] The invention belongs to the technical field of insect-proof, mildew-proof, moisture-proof and deterioration-proof preservation of traditional Chinese medicinal materials, and in particular relates to a method for preservation of prepared slices of traditional Chinese medicine. Background technique [0002] The traditional method of anti-corrosion, insect-proof, moisture-proof and anti-weaving of Chinese herbal medicines adopts sulfur fumigation, which is widely used in the processing and storage of Chinese medicinal materials, but sulfur fumigation will lead to SO 2 Or the residues of other sulfur-containing compounds, people's use may cause damage to the stomach, liver and immune system. Sulfur smoking will lead to the loss of active ingredients. For example, the main active ingredients in Angelica dahurica after sulfur smoking are significantly After sulfur fumigation, the amount of total alkaloids in pinellia significantly decreased, and the amount...
