To consider what instruments are needed for the research and development of natural products, we should first consider the steps of natural product research and development: separation and purification, molecular structure determination, laboratory preparation and pilot scale-up, preclinical pharmacological and toxicological experiments (involving the feeding, injection and external application of various experimental animals, the execution of experimental animals, anatomy and pathological analysis), drug clinical trials, drug analysis and monitoring in vivo, and comprehensive evaluation of drugs after clinical (after drug marketing). Environmental pollution and degradation should be considered for non-medical consumables, and physical and chemical properties of polymer materials should be evaluated (such as hardness, toughness, ductility, optical properties, acid resistance, etc.). ). So many instruments are used: 1. Various glass instruments used in chemical experiments, such as test tubes, test papers, glass rods, separatory funnels, distillers, filtering instruments, etc. 2. Various instruments used for instrumental analysis: chromatograph, moisture analyzer, mass spectrometer, spectrometer, biochemical analyzer, etc. 3. Feeding instruments for pharmacokinetics, pharmacodynamics and toxicology of experimental animals. 4. Various instruments used in clinical experiments: blood drug concentration detector, various instruments used for human pathological and toxicological analysis (biochemical analysis instruments will be used in some cases), 5. Non-medical items should also be tested and analyzed for environmental protection, such as concentrators and dust meters. The evaluation of polymer properties should use hardness tester, material ductility bending tester and material fracture analyzer.
