Annotation -
The aim of the course is to introduce students to isolation and analytical procedures required for working with plant material to successful isolate of various constituents and determination of the content of selected secondary metabolites using modern analytical methods. Students will learn the process of selecting and processing the starting material from extraction, separation to identification of its constituent metabolites and the possibility of modifying the structures of natural substances to increase stability, detection and biological activity, or bioavailability. The practical exercises also include in silico evaluation of isolated compounds.

Learning outcomes -

Theoretical knowledge of the subject Phytochemical Methods (GAPL002). Furthermore, knowledge of the basics of organic and analytical chemistry, including instrumental methods.
The subject Laboratory of Phytochemical Methods I builds on the knowledge and skills acquired in the subjects Phytochemical Methods, Chemistry of Natural Substances I. A graduate of the practical exercises in phytochemical methods knows the strategy of selecting and processing plant material from its collection, preparation of extracts with their subsequent analysis (TLC, chemical evidence reactions) and separation of compounds from prepared extracts by chromatographic methods. He is able to fractionate extracts by Flash chromatography (method development, setting parameters in the software of the instrument for separating compounds, as well as subsequent processing of fractions, including evaluation of the separation and composition of the obtained fractions).

Learning outcomes:
Based on the acquired knowledge and skills, students will:

  • select and assess the strategy for selecting plant material and its processing for the isolation of substances
  • define factors influencing the extraction processes of compounds from biogenic material
  • know the principles of separation and detection of substances using TLC and HPTLC, chemical evidence reactions
  • design a method for the separation of substances using Flash chromatography, including method development, setting parameters in the software, including evaluation of the separation and composition of the obtained fractions
