Problems solved by technology

[0002] In recent years, there have been many discussions about the extraction methods of traditional Chinese medicine, but the extraction rate of active ingredients is still the bottleneck of the modernization of the domestic traditional Chinese medicine pharmaceutical industry.
Although some new technologies have been introduced in the extraction and production of traditional Chinese medicine in China in recent years, such as ultrasonic field enhanced extraction, microwave extraction, supercritical fluid extraction, etc., the current mainstream is still the extraction technology; how to choose in the face of many traditional Chinese medicine extraction methods is a problem. It is a complicated problem, because it involves many factors such as production equipment and production conditions, plus the large scale of traditional Chinese medicine extraction today, especially considering continuous production, even if the results are obtained in the experiment, it will take a long time in actual conditions. practice test
There is also the new extraction process mentioned above. The extract is often a substance with a clear chemical structure, which is completely different from the production of traditional Chinese medicine. Therefore, manufacturers of traditional Chinese medicine cannot make up their minds to try new techniques, and producers are willing to follow the trend. to avoid the risk

Embodiment 1

[0025] Embodiment 1: a kind of Chinese medicine extraction method.

[0026] It includes the following steps:

[0027] (1) Pretreatment of medicinal materials includes: (1) crushing medicinal materials into segments with a length of 3-10cm; (2) stirring, spraying water and alcohol during stirring, the total mass of water and alcohol is 20% of the total mass of medicinal materials -30%, according to the weight ratio, the ratio of alcohol to water is 1:3-4; (3) sealed in a light-proof environment of 20°C-30°C for 1-2 days; The medicinal materials are soaked in the initial stage, and the water-insoluble active ingredients in the medicinal materials are extracted by alcohol at the same time, which provides the basis for efficient extraction in the later stage.

[0028] (2) Put it into the extraction tank and add water. According to the weight ratio, the ratio of medicinal materials: water is 1:12-14.

[0029] (3) Alcohol is added again; by weight, the ratio of medicinal materials...

Embodiment 2

[0036] Embodiment 2, the similarity with embodiment 1 will not be repeated, the difference is:

[0037] In step (1), the total mass of water and alcohol is 20% of the total mass of medicinal materials.

[0038] In step (1), the ratio of alcohol to water is 1:3 by weight.

[0039] In step (1), it is sealed and kept in a light-proof environment at 20°C for 1 day.

[0040] In step (2), the medicinal material: water ratio is 1:12 by weight.

[0041] In step (3), the ratio of medicinal material:alcohol is 1:0.02 by weight.

[0042] In step (4), the extraction tank was heated to 40° C. for 30 minutes.

[0043] In step (4), the extraction tank was heated to 100° C. within 1 min.

Embodiment 3

[0044] Embodiment 3, the similarities with Embodiment 1 will not be repeated, the difference is:

[0045] In step (1), the total mass of water and alcohol is 30% of the total mass of medicinal materials.

[0046] In step (1), the ratio of alcohol to water is 1:4 by weight.

[0047] In step (1), it is sealed and kept in a light-proof environment at 30°C for 2 days.

[0048] In step (2), the ratio of medicinal materials: water is 1:14 by weight.

[0049] In step (3), by weight ratio, the ratio of medicinal material:alcohol is 1:-0.08.

[0050] In step (4), the extraction tank was heated to 50° C. for 90 minutes.

[0051] In step (4), the extraction tank was heated to 150° C. within 1 min.
