1. Study the quality control of drugs, including the analysis and testing of the purity, stability and content of drugs, so as to ensure that the quality of drugs meets the national and industrial standards.

2. To study the analytical methods of drug components and their metabolites, so as to understand the metabolic process and pharmacodynamic mechanism of drugs in vivo and provide basis for drug research and development and optimization.

3. To study the pharmacokinetics and pharmacodynamics of drugs, including the absorption, distribution, metabolism and excretion of drugs in vivo, as well as the pharmacodynamic mechanism and efficacy evaluation of drugs, so as to provide theoretical and practical support for the clinical application of drugs.
