Advantages of Ultrafiltration Membrane Separation Equipment for Traditional Chinese Medicine Injection:
1. Ultrafiltration membranes have high rejection rates of macromolecular impurities, heat sources and bacteria, which can improve drug safety.
2. Ultrafiltration membrane filtration belongs to physical filtration without chemical reaction, and does not change the active ingredients.
3. Ultrafiltration membrane filtration belongs to cross-flow operation, and the membrane is not easily blocked.
4. Ultrafiltration membranes are imported from abroad with various qualifications, long service life and safety.
5. Choose hygienic grade material, conform to GMP certification;

Typical application of ultrafiltration membrane technology in traditional Chinese medicine:
1. Separation and Purification of Organic Acids, Glycosides, Alkaloids, Flavonoids and Polysaccharides by Ultrafiltration Membrane
2. Separation, Purification and Concentration of Oral Liquid, Injection, Extract and Granule of Traditional Chinese Medicine
mber of studies and practices have proved that there are still many problems in this process: first, the loss of effective ingredients, in addition, the effect of impurity removal is not ideal. Tannins, starches, resins and proteins in the extracts of traditional Chinese medicines are not easily removed by the traditional water-alcohol method, so the solid yield is still very high, which not only brings inconvenience and pain to patients, but also makes the preparations of traditional Chinese medicines easy to absorb moisture and deteriorate, and the taste of the preparations is poor.

Ultrafiltration Membrane Separation Technology for Traditional Chinese Medicine Injection:
Ultrafiltration membranes can intercept proteins and macromolecule compounds with radius ranging from 1 to 20 nm and molecular weight ranging from 1000 to 300000. It can also intercept colloidal particles of corresponding size. Ultrafiltration membranes with molecular weight rejection values of 10,000-30,000 can basically ensure the passage of active ingredients. The purpose of removing impurities and retaining active ingredients can be achieved by blocking impurities and pyrogens with molecular weight of tens of thousands to millions.
Application of Ultrafiltration Membrane Separation for Traditional Chinese Medicine Injection:
1. The pyrogen removal test of streptomycin sulfate (dihydrogen) was carried out in a small coiled ultrafiltration device with a molecular weight of 20,000. The results show that it is feasible to use ultrafiltration instead of traditional activated carbon to adsorb pyrogen in the production of streptomycin sulfate (dihydrogen).
2. A pharmaceutical company in Xi'an used sulfonated polyethersulfone membranes (SPES) with a molecular weight of 10,000 to remove pyrogen from Astragalus Injection by ultrafiltration and then adsorbed by activated carbon, so that the qualified rate of pyrogen fluctuated from the original to the current 100%.
3. Several kinds of compound Chinese herbal medicine injections such as Salvia miltiorrhiza and Gardenia jasminoides were prepared by ultrafiltration method in a domestic scientific research institute. The ultrafiltration product had good clarity and no precipitation appeared after 3 months. The contents of tannins, proteins and starches in injection were determined by ch
