Why the extraction technology of membrane technology in traditional Chinese medicine is more and more important in the extraction of traditional Chinese medicine？

The traditional Chinese medicine is the treasure of the Chinese nation for thousands of years of splendid culture, its efficacy is unique, and it occupies a very important position in the world medicine field. In the past thousands of years, the traditional Chinese medicine decoction, which is the main part of the water decoction, is the main way of the clinical use of the traditional Chinese medicine. At present, most of the Chinese traditional Chinese medicine manufacturers still use water as the basic extraction technology. The composition of the traditional Chinese medicine water extract is extremely complex, the content of the effective components is generally lower, and the traditional Chinese medicine water extract often contains non-medicinal components such as starch, protein, mucus, pigment, gum, pectin and the like, and also contains toxic components. There are about 7000 Chinese medicine products listed in our country, and more products still show the characters of the "Big, black, thick" And in particular, 80 to 95 percent of the solid preparation product is an invalid impurity and an auxiliary material, and the effective component accounts for 3 to 20 percent of the product quality.

Traditional extraction method

The traditional refining methods include chemical treatment, general mechanical filtration (such as plate frame, adsorption and high speed centrifugation, etc.), water extraction and alcohol precipitation, solvent extraction and so on. It often appears the phenomenon of back mixing, even precipitation, low effective ingredients in the product, so that the dosage of the preparation is large. There are also some problems, such as large solvent consumption, long production cycle, unstable product quality, high energy consumption when concentrated at high temperature, large quantity of waste water from production and extraction, resulting in environmental protection burden and so on. It is difficult to meet the needs of modernization and internationalization of traditional Chinese medicine.

Membrane separation and extraction

In order to realize the modernization of the traditional Chinese medicine, the quality of the traditional Chinese medicine product can be improved by applying the high-tech technology, and the effect of the traditional Chinese medicine "to coarse-grained" is obtained. The membrane separation technology has the characteristics of energy conservation, environmental protection, high efficiency and the like, and is widely recognized as a major high-technology for the most promising future of the century, and has better application in the fields of food, medicine, chemical industry, water treatment, environmental protection and the like, It is also considered to be one of the urgent need to promote the Chinese traditional Chinese medicine pharmaceutical industry. In recent years, China's traditional Chinese medicine industry also has a number of enterprises to take the lead in adopting membrane separation technology to obtain great economic and social benefits. In addition, the absorption method of the traditional Chinese medicine is the rate of absorption is directly related to the particle size of the effective component of the drug, and the separation principle of the membrane separation technology, namely the pore size screening, is not matched. Therefore, a novel traditional Chinese medicine refining technology with membrane separation as the core is established to break through the traditional "hydro alcoholic method", and the traditional Chinese medicine industry "solid-liquid separation, purification and concentration" production process is integrated with the integrated membrane integration technology, so that the high-efficiency, environment-friendly, stable and intelligent control of the production of the traditional Chinese medicine is realized.

Application of membrane Integration Technology in preparation of traditional Chinese Medicine

Through various membrane combinations such as microfiltration, ultrafiltration, nano filtration or reverse osmosis, the integrated technology of traditional Chinese medicine preparation membrane is formed. The most widely used methods are Chinese herbal extract, oral liquid, injection and so on. The application of membrane integration technology in the field of traditional Chinese medicine can improve the product recovery rate of 5% and purity of 20%, even higher than that of traditional Chinese medicine. The production cycle is reduced by about half, the land area is smaller, and the energy consumption is reduced by 30%.

Comprehensive Utilization of waste Resources of traditional Chinese Medicine

In the production of the traditional Chinese medicine, the washing liquid of the raw material and the extracted residue washing liquid or the extracting solution contain the target product or other effective components, and are generally directly discharged as waste water due to low concentration and difficulty in recycling. The membrane separation technology can be used as a more economical purification method, and the effective components in the membrane separation technology can be recovered well
