Abstract:
Thousands years of experiences reveal that the water extract is the safest and effective carrier for traditional Chinese medicine. Membrane technology is a powerful tool for the cluster-screening of the small molecules from Chinese herbal. However, the lack of microscopic understanding of the water extracts of traditional Chinese medicine restricted the advantages of membrane technology. In this study, the key technologies to address these issues: the "solution structure" of traditional Chinese medicine chemical composition (ie: the microstructure and macroscopic properties of the solvent material in solution) and the pore steric hindrance, a variety of index components of Huanglianjiedutang(HLJDT) as a model drug, by a) atomic force microscopy, dynamic laser light scattering, high-resolution nuclear magnetic resonance of molecular biophysics and other means of compound Chinese herbal medicinal ingredients of the "solution structure" characteristics; b) elaborating the mechanism of competitive filtration behavior by learning principles of solvent effects arising from the ultrafiltration membrane mass transfer process; c) exploring the correlation betwwen "solution structure" of the chemical medicine system and the membrane material micro-structure by using the computer technology. The purpose of this study is: a) deepening overall concept-based modern research of Chinese herbal compound by integrating of a multidisciplinary approach; b) establishing a specific membrane separation technology which can obtain small molecule groups from traditional Chinese medicine; c) providing a theoretical basis for new Chinese medicine; d) solving the key problems of Chinese herbal compound preparation and promoting the development of membrane science and technology.
