Sustainable Membrane Technologies for By-Product Separation of Non-Pharmaceutical Common Compounds

Abstract

The Chinese pharmaceutical industry and traditional Chinese medicine (TCM) are both vital components of Chinese culture. Some traditional methods used to prepare TCMs have lost their conformity, and as a result, are producing lower-quality medicines. In this regard, the TCM sector has been looking for new ways to boost productivity and product quality. Membrane technology is environmentally-friendly, energy-saving technology, and more efficient than traditional technologies. Membrane separation is the most effective method for separating and cleaning the ingredients of the non-pharmaceutical common compounds from traditional Chinese medicine (TCM). Membrane technology is currently being employed for the concentration, purification, and separation of TCMs. This review paper discusses how membranes are fabricated and their role in non-pharmaceutical common compound separation and TCM purification. Accordingly, the membrane applicability and the technological advantage were also analyzed in non-pharmaceutical common compound separation. Researchers pay attention to the choice of membrane pore size when selecting membranes but often ignore the influence of membrane materials and membrane structure on separation, resulting in certain blindness in the membrane selection process.
