Through pharmacodynamic test and clinical observation, it is proved that a set of mature technological procedures can not only ensure the efficacy, but also improve the efficacy after purification. However, there are many technical problems that must be paid attention to in the application, such as the selection of resin model. The specifications and quality requirements of the resin itself play a decisive role in the purification effect and stability of the extract of traditional Chinese medicine. Different models have different properties. The components of the water extract of traditional Chinese medicine are extremely complex, so it is not suitable to use a type of resin for purification. In the process of purification and purification, the pharmacodynamic experimental methods related to the effect must be selected and tracked according to the needs of diagnosis and treatment of diseases. At the same time, the effective chemical components of the drug must be tracked to ensure that the effective components are not lost, the efficacy is not reduced, and the quality is stable and reliable in the process of purification and purification. The process conditions such as resin dosage, large adsorption capacity, adsorption and elution speed, height and diameter of resin column, type and concentration of elution solution, etc. must be selected first to ensure the quality of drugs. Only the correct process conditions can ensure good efficacy.
