Defects in traditional extraction and concentration of traditional Chinese medicine
1. Organic solvents may cause denaturation and failure of active ingredients, increase production costs, and also cause environmental pollution.
2. The process involves complex steps, long cycles, high energy consumption, and significant process losses, especially when the content of extracted active ingredients is too low, resulting in low separation efficiency.
3. The removal rate of non pharmacological components and the concentration rate of effective parts are not high enough, the medicinal dosage is large, and the clinical efficacy cannot be fully utilized.
4. High temperature operation is often used, which can easily cause the decomposition of thermosensitive medicinal ingredients.
5. Overemphasizing the role of individual components can cause traditional Chinese medicine to lose its original compound characteristics and affect its efficacy.

The membrane separation process is a pure physical process that has the characteristics of no phase change, energy saving, small volume, and separability. It is suitable for organic compounds with different compositions,

Based on the molecular weight of organic matter, different membranes are selected and appropriate membrane processes are chosen to achieve membrane flux and rejection rate, thereby improving production yield

Reduce investment scale and operating costs. The application of membrane separation technology in the refining and concentration of plant extracts has optimized the process of traditional Chinese medicine refining and shortened the production cycle,

Improved the effective ingredients of the formulation, saved a lot of solvent consumption, and improved the quality of the product.

Advantages of membrane separation:

1. Reduce production processes and shorten production cycles.

2. Save organic solvents and other raw materials, reduce production costs, and promote safe production in factories.

3. The membrane process does not produce new substances, can maintain the original formula components, and increase the content of effective parts.

4. The impurity removal effect is good, which can significantly improve the clarity of the formulation and greatly extend the storage time.

5. It can effectively remove bacteria, heat sources, etc., avoiding damage and loss of medicinal ingredients or precipitation caused by heating sterilization.
