Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicine preparation and processing, and in particular to a preparation method of Chinese medicine decoction piece Typha acuminata charcoal. Background Art

[0002] Processing refers to the necessary processing of drugs before they are used or made into various dosage forms, including general treatment and arrangement of raw medicinal materials and special treatment of some medicinal materials. In ancient times, it was called "paozhi", "xiuzhi", "xiushi", etc. Due to the wide variety of Chinese medicines and complex ingredients, before making various dosage forms, they should be processed according to the different requirements of formulas, preparations and medical treatments, and according to the characteristics of each medicinal material itself, so that they can not only exert sufficient therapeutic effects but also avoid or reduce the adverse reactions of the drug itself, thereby meeting the purpose of clinical medication to the greatest extent. Charcoal making is a Chinese medicine processing method that treats the cleaned or cut medicinal materials with high temperature to carbonize the outside of the medicinal materials and retain the inherent properties inside.

[0003] Typhae pollen belongs to the genus Typha of the family Typhaceae, and is the dried pollen of Typha orientalis or plants of the same genus. Typhae pollen is a famous Chinese medicine with multiple functions such as hemostasis, blood stasis removal and stranguria relief. Typhae pollen charcoal made from raw Typhae pollen after carbonization has obvious anti-hemorrhagic effect and is widely used in clinical anti-thrombosis, wound and bleeding. The traditional preparation method of Typhae pollen charcoal is to use a stir-frying machine to mechanically stir-fry Typhae pollen to carbonize it to obtain Typhae pollen charcoal. However, since Typhae pollen is in powder form, it is easy to fly during stir-frying, which not only causes a large loss of medicinal materials, but also easily causes combustion and explosion. Summary of the invention

[0004] In view of this, the object of the present invention is to provide a method for preparing Chinese herbal medicine Puhuang charcoal to overcome the above-mentioned defects in the prior art.

[0005] To achieve the above object, the present invention provides a method for preparing Chinese medicinal piece Puhuang charcoal, which comprises wetting Puhuang with vinegar solution, mixing it evenly, and then frying it in a medicine frying machine to obtain Puhuang charcoal.

[0006] Furthermore, the pH value of the vinegar solution is 3-5.

[0007] Furthermore, the usage amount of the vinegar solution is 10-20% of the weight of Pollen Typhae.

[0008] Furthermore, the vinegar solution is edible white vinegar solution.

[0009] Furthermore, the frying temperature of the medicine frying machine is controlled to be 200-250°C, the rotation speed is 20-30r / min, and the frying time is 18-25min.

[0010] Furthermore, the frying temperature of the medicine frying machine is controlled to be 220° C., the rotation speed is 25 r / min, and the frying time is 20 min.

[0011] Furthermore, the medicine frying machine is an automatic temperature-controlled medicine frying machine.

[0012] Compared with the prior art, the method for preparing the Chinese medicine piece Puhuang charcoal provided by the present invention uses an acidic solution to wet the powder of the medicinal material before frying, which can avoid the occurrence of powder explosion, reduce the ash and flying of the medicinal material, and reduce the loss of the medicinal material. In addition, in the theory of traditional Chinese medicine, acidic substances have a convergence effect, and the efficacy of Puhuang charcoal has a hemostatic function. A certain amount of acidic solution with a certain pH value is added during the preparation of Puhuang charcoal, and the astringent effect of the acidic solution is utilized to enhance the hemostatic function of Puhuang charcoal. The preparation method provided by the present invention is simple to operate, is not easy to produce coking, and the charcoal medicine has a uniform color, which fully complies with the preparation principle of "frying charcoal to preserve its properties".

After frying, take out the Puhuang charcoal, spread it out to cool, and then weigh it to obtain 89.6 kg of Puhuang charcoal, and the medicinal material loss rate is 10.4%.

[0029] Comparative Example 5:

[0030] Take 100 kg of raw Puhuang powder (medicinal material batch number Y231201) to be fried, first mix and moisten it with 8 kg of white vinegar solution (pH = 3), and then put it into an automatic temperature-controlled medicine frying machine for frying.

After frying, take out the Puhuang charcoal, spread it out to cool, and then weigh it to obtain 89.1 kg of Puhuang charcoal, and the medicinal material loss rate is 10.9%.

[0031] The comparison of the processing loss of Pollen Typhae charcoal in each embodiment and comparative example is shown in Table 1 below.

[0032] Table 1. Comparison of the loss of pollen charcoal during processing

[0033]

[0034] As can be seen from Table 1, compared with the traditional processing method of Puhuang charcoal in Comparative Example 1, the processing methods of Examples 1 to 3 reduce the loss rate of medicinal materials from 14.9% to 6.6%. The processing methods of Examples 1 to 3 significantly reduce the waste of medicinal materials and greatly reduce the production cost. However, the amount of white vinegar solution added also has a certain range. If it is added too little, the medicinal materials cannot be completely wetted and the powder still occurs (see Comparative Example 5). If it is added too much, the medicinal materials cannot be fully carbonized during frying (see Comparative Example 4). The loss rate of medicinal materials is still not significantly suppressed. After comprehensive experiments by the inventor, it is determined that when the amount of white vinegar solution added is 10-20% of the weight of Puhuang, the loss rate of medicinal materials can be controlled to 6.6%.

[0035] The following is a trauma hemostasis test on the Typha Pollen charcoal prepared in the above examples and comparative examples, as follows:

[0036] Take 24 healthy, clean New Zealand rabbits, divide them into 8 groups, remove hair around the ear vein, and anesthetize them with 2% sodium pentobarbital 35mg / kg ear vein injection. After disinfection with 75% medical alcohol, each rabbit cuts the ear vein at 7cm away from the ear tip, and sprinkles 3g of Typhae Pollen Carbon powder obtained in equal amounts of Examples 1 to 3 and Comparative Examples 1 to 5 after free bleeding for 5s, and uses a 50g weight as an external force to press the wound, observes the bleeding condition of the wound every 5s, and absorbs the blood with absorbent cotton, records the weight of absorbent cotton before and after absorption, and calculates the amount of bleeding. Record the time from cutting off the ear vein to no longer bleeding as the hemostasis time, and repeat 4 times for each group, and the results are shown in Table 2.

[0037] Table 2. Traumatic hemostasis test results

[0038]

[0039]

[0040] The results in Table 2 show that in the hemostatic test of rabbit ear vein injury, the hemostatic effect of the Puhuang charcoal prepared in Examples 1 to 3 and Comparative Examples 4 to 5 is better than that of the Puhuang charcoal prepared in Comparative Examples 1 to 3, indicating that adding a certain amount of white vinegar solution with a certain pH value during the preparation of Puhuang charcoal can enhance the hemostatic function of Puhuang charcoal.

[0041] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
