CHE 4100 - MEDICINAL PLANT ANALYSIS
credits: 3.0
Will emphasize the use of instruments in the quantification and identification of compounds in plants, including polyphenols in wine, hops extracts in beer, herbal extracts, and psychoactive drugs. Instrument optimization and application will be studied within the context of atomic absorption spectroscopy, gas chromatography, and liquid chromatography. Quality assurance and quality control procedures will be discussed and practiced through designated experiments. Laboratory experiments are designed to give students as much hands-on experience operating and troubleshooting the instruments. This course is designed to give students the experience and confidence to tackle complex chemical problems relevant to plants using modern scientific instrumentation. Objectives: A) Interpreted and presented the results of instrumental analysis; B) Designed experiments using modern instrumentation to answer a research question; C) Developed a chromatographic and detection method for the separation of drugs, pesticides, and/or metabolites; D) Followed a quality assurance - quality control procedure; E) Quantified, with high accuracy and precision, medicinal compounds in plants. Method of Instruction: Laboratory experiments will be designed to quantify and develop methods for the analysis of compounds in plants and plant extracts. Each laboratory experiment is designed as an open-ended research question. Students prepare a written proposal, which consists of solution preparation, instrument optimization, and data analysis for the experiment. Students present their plans to the instructor then execute their plan in the laboratory. Students write a report, which presents the methods, results, and discussion, for each experiment. Students would receive feedback on the proposal, report, and during the execution of the experiment. Method of Evaluation: Experiment Proposals 25%, Reports 30%, and Final Project 45%.
