Example Embodiment

[0075] Example 1.

[0076] This embodiment provides a microwave extraction method of cardiovascular Chinese medicine prescriptions, which includes the following steps:

[0077] 1) Use an electronic analytical balance to accurately weigh 40g coix seed, 12g orange, 20g aconite, and 20g red ginseng;

[0078] 2) Wash the weighed Chinese medicinal materials and put them into the microwave extractor;

[0079] 3) Weigh 800 mL of distilled water with an electronic balance and pour it into the microwave extractor;

[0080] 4) Soak for 30 minutes;

[0081] 5) Set the power of the microwave extractor to 400-1200W, start the extraction of the Chinese medicine compound, and take samples every 8 minutes until 40 minutes;

[0082] 6) After cooling the extracted sample, put it in the refrigerator for later use.

Example Embodiment

[0083] Example 2.

[0084] In this example, a comparative experiment was set up to analyze the influence of microwave power on the concentration of effective components in the extract. Specifically: under the condition that the soaking time is 30min, the extraction time is 32min, and the number of extraction times is 1, the power of the microwave extractor in step 5) is set to 400W, 600W, 800W, 1000W, 1200W for extraction, After the end, determine the concentration of the effective ingredients in the extract. The influence of microwave power on the concentration of the effective ingredients in the extract is as follows: figure 1 Shown.

[0085] by figure 1 It can be seen that ginsenoside Rg 1 The concentration increases with the increase of microwave power. This is because the greater the microwave power, the greater the microwave energy, and the faster the liquid in the cell vaporizes into a gaseous state, so that the cell wall and cell membrane are damaged more quickly and to a ...

Example Embodiment

[0086] Example 3.

[0087] In this example, a comparative test was set up to analyze the effect of extraction time on the concentration of the effective components in the extract. Specifically: under the conditions of immersion time of 30min, microwave power of 1200W, and extraction times of 1 time, extraction was performed at extraction times of 8min, 16min, 24min, 32min, and 40min, respectively, and the effective components in the extract were determined after the extraction. The effect of extraction time on the concentration of active ingredients in the extract is as figure 2 Shown.

[0088] The results showed that overall, as the extraction time increased, the ginsenoside Rg in the extract 1 The concentration gradually increased. This is because the microwave radiation time increases, the time the microwave radiation acts on the cells increases, the cell wall damage increases, and more effective ingredients are precipitated from the cells, so the ginsenoside Rg in the extract...

Abstract

The invention relates to an extraction method of traditional Chinese medicine compound preparations and particularly relates to a microwave extraction method for a cardiovascular traditional Chinese medicine prescription. By utilizing microwaves, liquid water such as cell sap in vegetable cells is rapidly facilitated to change into vapor, so that the pressure in the cells is increased, the cell membranes and cell walls are broken, and the extraction time of the active ingredients can be shortened when the active ingredients are dissolved into the solvent. Compared with the traditional heatingextraction method, the microwave-assisted extraction technology can obviously shorten the extraction time of the active ingredients and has the advantages of being high-efficiency and energy-saving.

Description

technical field [0001] The invention relates to an extraction method of a compound traditional Chinese medicine preparation, in particular to a microwave extraction method of a cardiovascular Chinese medicine prescription. Background technique [0002] In recent years, with the trend of "returning to nature" and the country's strong advocacy of local culture, Chinese medicine has attracted more and more attention. At the same time, traditional Chinese medicine has become a research hotspot for scholars. The extraction of chemical components of traditional Chinese medicine is the premise and key of modern research on traditional Chinese medicine. At present, there are various extraction methods of natural products. Although commonly used traditional methods such as decoction and reflux extraction can extract active ingredients to varying degrees, they are not suitable for ingredients with poor thermal stability. [0003] Microwave is an electromagnetic wave with a waveleng...
