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 t

Example Embodiment

[0067] Example 1.

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

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

[0070] 2) Wash the weighed Chinese medicinal materials and put them into the microwave extractor;

[0071] 3) Weigh 800 mL of distilled water with an electronic balance and pour 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) Use an electronic analytical balance to accurately weigh 12g of Amomum villosum, put it in the microwave extractor, mix and cook for 10 minutes;

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

Example Embodiment

[0076] Example 2.

[0077] In this example, a comparative experiment was set up to analyze the influence of microwave power on the extraction effect of arecoline. Specifically: under the conditions of immersion time of 30min and extraction time of 40min, the power of the microwave extractor in step 5) is set to 600W, 800W, 1000W, 1200W for extraction, and the effective components in the extract are determined after the extraction is completed The concentration of arecoline and the influence of microwave power on the extraction effect of arecoline are as follows: figure 1 Shown.

[0078] by figure 1 It can be seen that under the same microwave radiation time, with the increase of microwave power, the concentration of arecoline obtained by extraction first increases and then decreases. When the microwave power is 1000W, the concentration of the extracted arecoline reaches its maximum value, which is 3.91μg / mL. Therefore, the optimal microwave power for arecoline extraction is 1000W...

Example Embodiment

[0081] Example 3.

[0082] In this example, a comparative experiment was set up to analyze the influence of microwave radiation time on the extraction effect of arecoline at a microwave power of 600W. Specifically: Under the conditions of immersion time of 30min and microwave power of 600W, samples are taken every 8 minutes for extraction. After the extraction, the concentration of the active ingredient arecoline in the extract is determined. The effect of extraction time on the extraction effect of arecoline Such as figure 2 Shown.

[0083] The results showed that under 600W power, with the increase of microwave radiation time, the concentration of arecoline obtained by extraction also increased. The concentration of arecoline obtained by the extraction reached its maximum value at 1.29μg / mL when the microwave was irradiated for 40min. Under 600W power, the liquid medicine starts to boil in about 22 minutes. 22 minutes ago, the arecoline in the cells was not extracted, so the ...

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...
