Problems solved by technology

[0012] However, with the acceleration of the pace of society and the popularization of western medicine, the utilization rate of traditional Chinese medicine has been declining year by year
Although traditional Chinese medicine has many outstanding advantages, there are mainly 1) less side effects and basically non-toxic; 2) the use of traditional Chinese medicine can be changed according to the quality of the symptoms, so it has the flexibility of treatment; Treating the symptoms and treating the root cause, but traditional Chinese medicine still shows many shortcomings, mainly including ①it takes a lot of time and energy to prepare and cook, which is not suitable for modern fast-paced life and emergency medication needs; ②the utilization rate of medicinal materials is low and the content of impurities is high; ③most of them are It is the patient himself or his family members who are responsible for decocting the medicine, and there is a possibility of improper operation, resulting in changes in the efficacy of the medicine

Embodiment 1

[0068] This embodiment provides a method for microwave extraction of traditional Chinese medicine prescriptions for gastrointestinal diseases, comprising the following steps:

[0069] 1) Accurately weigh 12g of Jilin ginseng, 18g of betel nut, 20g of peach kernel, and 10g of black medicine with an electronic analytical balance;

[0070] 2) Put the weighed Chinese medicinal materials into the microwave extractor after cleaning;

[0071] 3) Weigh 800mL of distilled water with an electronic balance, and inject it into the microwave extractor;

[0072] 4) Soak for 30 minutes;

[0073] 5) Set the power of the microwave extractor to 600-1200W, and cook for 30 minutes;

[0074] 6) Accurately weigh 12g Amomum seed with an electronic analytical balance, put it into a microwave extractor, mix and decoct for 10 minutes;

[0075] 7) Take a sample every 8 minutes for a total of 5 times. After the extract is cooled to room temperature, put it in the refrigerator for later use.

Embodiment 2

[0077] In this embodiment, by setting up comparative experiments, the influence of microwave power on the extraction effect of arecoline is analyzed. Specifically: under the condition that the soaking time is 30min and the extraction time is 40min, the power of the microwave extractor in step 5) is respectively set to 600W, 800W, 1000W, and 1200W for extraction, and the active ingredients in the extract are determined after the extraction The concentration of arecoline and the influence of microwave power on the extraction effect of arecoline are as follows: figure 1 shown.

[0078] Depend on figure 1 It can be seen that under the same microwave irradiation time, with the increase of microwave power, the concentration of arecoline extracted first increased and then decreased. When the microwave power was 1000W, the concentration of arecoline extracted reached the maximum value, which was 3.91μg / mL. Therefore, the optimal microwave power for arecoline extraction is 1000W.

Embodiment 3

[0082] In this embodiment, by setting up comparative experiments, the influence of microwave radiation time under microwave power of 600W on the extraction effect of arecoline is analyzed. Specifically: Under the conditions of soaking time of 30min and microwave power of 600W, a sample was taken every 8 minutes for extraction, and the concentration of the active ingredient arecoline in the extract was measured after the extraction, and the influence of extraction time on the extraction effect of arecoline Such as figure 2 shown.

[0083] The results showed that under the power of 600W, with the increase of microwave irradiation time, the concentration of extracted arecoline also increased continuously. After microwave irradiation for 40 minutes, the concentration of arecoline extracted reached the maximum value of 1.29μg / mL. Under the power of 600W, the liquid medicine starts to boil in about 22 minutes. Before 22 minutes, the arecoline in the cells was not extracted, so t...

Abstract

The invention relates to an extraction method for Chinese medicinal formulae, and specifically relates to a microwave extraction method for a gastroenteropathy Chinese medicinal formula. Liquid watersuch as a cell sap inside plant cells is quickly improved to become water vapor by using microwave, the pressure inside cells is increased, cell membranes and cell walls are broken, and then the effective ingredient of arecoline is dissolved into a solvent so that the extraction time of the effective ingredient of arecoline can be shortened; and compared with a traditional heating extraction method, a microwave-assisted extraction technology can obviously shorten the extraction time of the effective ingredient of arecoline, and has the advantages of high efficiency and energy saving.

Description

technical field [0001] The invention relates to an extraction method of a traditional Chinese medicine compound preparation, in particular to a microwave extraction method of a traditional Chinese medicine prescription for gastroenteropathy. Background technique [0002] Microwave extraction technology, referred to as MAE, is a new extraction and separation method proposed by Hungarian scholar Ganzler in 1986. Ganzler used microwave ovens to extract gossypol from cottonseeds, and found that the consumption of solvent was less, the extraction time was shorter, and the extraction efficiency was much higher than that of Soxhlet extraction and ultrasonic extraction. Since then, microwave extraction technology has been valued by various countries and has become a research hotspot in the new century. With the in-depth research and development of microwave extraction technology, microwave extraction technology has been widely used in various fields, mainly in soil analysis, food c...
