Liu Zhiqiang, male, born in 1962, is a researcher and doctor of science. He graduated from the Department of Chemistry of Jilin University in 1984 with a bachelor's degree in science, obtained a master's degree in chemistry of Jilin University in 199, and obtained a doctor's degree in chemistry of Jilin University in 1996. From January 1997 to January 1999, he worked as a postdoctoral researcher in the postdoctoral mobile station of Changchun Institute of Applied Chemistry, Chinese Academy of Sciences. He is currently the director of the Key Laboratory of Mass Spectrometry in Jilin Province, the director of the Chemistry Laboratory of Traditional Chinese Medicine in Jilin Province, the member of the Academic Committee of Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, the director of the new drug research laboratory, and the project leader of the new drug research group of traditional Chinese medicine.

As the project leader, he has undertaken more than ten scientific research projects, such as the Ninth Five-Year Plan key research project of the Ministry of Science and Technology, the Ninth Five-Year Plan national climbing plan pre-selection project of the Ministry of Science and Technology and state administration of traditional chinese medicine, the knowledge innovation project of China Academy of Sciences, the outstanding youth fund project of Jilin Science and Technology Department, and the Ninth Five-Year Plan key project of Jilin Science and Technology Department. He has published more than 3 academic papers, won one third prize for scientific and technological progress of the Ministry of Education, applied for four patents and obtained the Ministry of Education.

in recent years, with modern soft ionization mass spectrometry (matrix-assisted laser desorption ionization time-of-flight mass spectrometry, electrospray multi-stage tandem mass spectrometry) as the research means, and based on serum pharmacology, pharmacokinetics and the principle of non-* * valence complex, a lot of exploratory research has been carried out on the chemical substance basis, compatibility law, detoxification mechanism and Chinese medicine processing theory of Chinese medicine compound. In order to study the prescription theory of Chinese medicine compound and the scientific connotation of Chinese medicine processing, The establishment of a new method for screening effective components of traditional Chinese medicine at molecular level has laid a theoretical foundation, and on the basis of exploring the material basis and mechanism of action of traditional Chinese medicine compound, the traditional compound has been transformed to create a new compound that meets international standards; In addition, under the guidance of modern scientific theory and by means of modern separation technology, the research on new drug development, quality control standards, fingerprint and detection methods of pesticide residues and heavy metals in authentic medicinal materials in Changbai Mountain has been carried out, and great achievements have been made.
