Traditional Chinese medicine contains very complex chemical components, including carbohydrates, amino acids, proteins, greases, waxes, enzymes, pigments, vitamins, organic acids, tannins, inorganic salts, volatile oils, alkaloids and glycosides. These components have both effective ingredients and ineffective impurities, and if the impurities are not removed as much as possible, the quality and stability of preparations will be affected. One of the main reasons causing the precipitation of traditional Chinese medicine preparation products and low clarity is that the liquid contains tannins, proteins, macromolecular substances and other substances.
Many traditional Chinese medicine enterprises in China try to replace the traditional processes by using the microfiltration membrane filtration, and the microfiltration membrane filtration separation technology can filter protein, starch, pectin, tannin and other substances in the extract, while there is no residue in the effective ingredients of traditional Chinese medicines.
For the special treatment demand of certain liquids, the integrated membrane separation process which organically combines the ceramic membrane separation technology with the organic membrane ultrafiltration and nanofiltration separation technology is adopted to form the refined liquids of stepwise filtration, separation and purification, so that the advantages of two types of membrane separation can be reasonably applied to apply to extract and refine Chinese patent drugs.
The integrated membrane separation process is applied to the extraction of traditional Chinese medicines, which has the following advantages:
