The ingredients of Chinese herbal medicines are complex, and the extracts can be further separated and purified to obtain the single required pharmaceutical ingredients. The extraction of traditional Chinese medicine prescriptions is to use modern scientific and technological methods to extract reasonable components to improve the essential quality and clinical medical efficacy of traditional Chinese medicine preparations, so that traditional Chinese medicines can give full play to their desired effects.

In industrial production, concentrated extraction is a very critical step. The processing methods, production process selection and equipment configuration of concentrated extraction will immediately endanger the quality and clinical medical efficacy of traditional Chinese medicine, so it must be paid great attention.

Compared with the traditional methods of suction filtration, filtration, response, alcohol precipitation, epoxy resin adsorption, etc., the actual effect is not good at the level of response, purification and special Chinese medicine extracts. In addition, there are still problems such as difficulty in over-consideration, clogging of epoxy resin pores, high consumption of alcohol precipitation agent, high energy consumption in high-temperature concentration, large amount of production and extraction sewage, and heavy burden on environmental protection.

It is understood that the frying method is a traditional leaching method that was used earlier in my country. Generally, ceramics, sand pots or copper pond porcelain containers are used instead of frying pans to prevent the color of pure grain wine. When heating immediately, it can be often mixed to prevent the part of the Chinese herbal medicine from being overheated and easily burnt.

"The decoction method is relatively simple, and most of the ingredients of the medicine can have different levels of suggestions, but the traditional Chinese medicine contains volatile components and reasonable components that are easily destroyed by heat, so this method cannot be used. In addition, for Chinese herbal medicine Due to the sugar content of the material, the syrup is thicker after frying, and it is more difficult to over-constrain it.

In recent years, with the continuous development trend of Chinese medicine extraction and separation technology, the high-tech technologies used in Chinese medicine extraction and separation include: supercritical fluid purification, membrane separation, ultrafine powder, Chinese medicine inclined plate sedimentation tank separation, semi-bionic technology extraction, ultrasonic extraction , vortex extraction, working pressure backflow extraction, enzymatic method, macroporous resin adsorption, ultrafiltration membrane, molecular distillation, etc.

Compared with traditional Chinese medicine extraction methods, Chinese medicine extraction technology has the advantages of high extraction purity, easy operation, resource saving, short production cycle time, low solvent-free content, good product quality, and easy to discover new specificities in pure plants. components, volatile components and less damage to physiologically active substances.

In addition, the extraction machinery and equipment of Chinese herbal medicines are also constantly changing in operation. For example, some traditional Chinese medicine extractors use the bubble effect caused by ultrasound to speed up the entry of the solvent into the body cells, and use the organic chemical components in the body cells to quickly migrate into the solvent, resulting in a difference in the concentration value inside and outside the body cells, and promoting the concentration of organic chemical components from the body. The higher aqueous solution diffuses to the lower concentration aqueous solution, so as to achieve the purpose of separating and extracting the components of traditional Chinese medicine. In addition, the extraction rate of traditional Chinese medicine extraction machines is also continuously improving, which can extract all components of somatic cell chemicals in a relatively short period of time.

According to the detailed introduction of the industry department, when the green phytochemicals are ultrasonically applied in the solvent, although the cavitation bubbles caused by the ultrasonic wave will crack in an instant, the solvent will still be rapidly released due to the ultrasonic effect. It penetrates into the internal body cells of chemical substances, accelerates the mutual penetration and melting of solvents and reasonable components in Chinese herbal medicines, and reduces residues.

In addition, the extraction and processing technology of traditional Chinese medicine has been gradually popularized and improved in recent years. The separation and processing technology of contemporary traditional Chinese medicine is to use the difference in the content of organic chemical components to achieve the purpose of separation. The use of traditional Chinese medicine prescriptions is mainly to filter out germs, particulate matter, biological macromolecules (colloidal solution, tannin, protein, sugar content) residue or fade.
