Embodiment 1
[0022] Embodiment 1: A kind of preparation method of fresh toad skin superfine powder
[0023] 1) Take fresh toad skin and dry it continuously for at least 18 hours at a temperature of -50°C and a pressure of 20 Pa to obtain fresh toad skin;
[0024] 2) The freeze-dried fresh toad skin is ultrafinely pulverized in a vibrating ultrafine pulverizer at a temperature of -25°C for at least 5 minutes, until it passes through a 10-mesh sieve to obtain superfine toad skin powder.
[0025] In the step 1) of Example 1, the fresh toad skins are all fresh toad skins obtained from live toads killed or directly purchased from the market. The temperature in step 1) can be -45°C, -48°C, -53°C and -55°C, the pressure can be 15Pa, 18Pa, 23Pa or 25Pa, and the temperature in step 2) can be -30°C, -28°C, -26°C, -24°C and -20°C.

The invention discloses a preparation method of fresh toad skin ultra-fine powder, and belongs to the technical field of traditional Chinese medicine preparations. The preparation method comprises the following processing steps: 1) continuously drying fresh toad skin for at least 18 hours under the conditions that the temperature is minus 55 DEG C to minus 45 DEG C and the pressure is 15-25Pa; 2) carrying out ultra-fine crushing on the frozen and dried fresh toad skin at minus 30 DEG C to minus 20 DEG C until the powder completely passes through a 100-mesh sieve, so as to obtain the toad skin ultra-fine powder. The preparation method has the following beneficial effects: 1) the fresh toad skin is frozen and dried, so that the effective components of the existing crude drugs can be kept to the maximal extent due to the fact that the overall drying process is carried out at a low temperature; the mucus character can be completely kept due to the fact that the volume of the frozen and dried fresh toad skin is not destroyed; 2) the fresh toad skin particles are crushed to be smaller that the particle sizes of cells by adopting ultra-fine crushing; dissolving-out of the effective components is accelerated; the fussy extraction work is reduced; all components of the drugs are kept, and accord with the overall view of the traditional Chinese medicine.
Description
technical field [0001] The invention belongs to the technical field of traditional Chinese medicine preparations, and in particular relates to a preparation method of superfine powder of fresh toad skin. Background technique [0002] Toad skin has the effects of clearing away heat and detoxification, diuresis and swelling, treating carbuncle, swelling, scrofula, tumor, malnutrition, abdominal distension, and chronic bronchitis. At present, toad skin has been widely used clinically, but most of its research focuses on dried toad skin. Folk remedies record that fresh toad skin is directly or powdered externally on tumor-related acupoints to play a therapeutic role. However, the utilization rate of the active ingredients of toad skin that has not been deeply processed is low, the dosage is large, and the curative effect is not obvious. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to design and pro...
