Enhancing the Advanced Nature of Natural Product Chemistry Laboratory Courses with New Research Findings: A Case Study of the Application of Berberine Hydrochloride in Photodynamic Antimicrobial Films

Natural products chemistry experiment courses are vital practical part built upon theoretical foundations. However, these verification-focused experiments lack depth and hinder the development of students’ comprehensive abilities. To address this issue, we proposed integrating new scientific research findings into the design of comprehensive experiments, incorporating the concept of “double carbon”, and enhancing the depth of the course. In this experiment, we introduced cutting-edge research on photodynamic antimicrobial food packaging films with high fluorescence intensity into natural product chemistry experiments. Specifically, we incorporated berberine hydrochloride, a naturally occurring aggregation-induced emission agent, with phytic acid to create a salt that was added to the food packaging film, resulting in a photodynamic antimicrobial film with strong fluorescence. This experiment combined the fields of natural product chemistry, aggregation-induced emission, and food microbiology, and encouraged students to become familiar with the research process of theory-experiment-characterization-analysis. Through this integration, students could enrich their comprehensive knowledge, strengthen their practical skills, and foster their innovation consciousness, thus contributing to the cultivation of top talents in the field of forest chemical industry.
