31865 - Extraction of Phyto-derivatives I

Learning outcomes

At the end of the course, the student knows the basics of extracting active ingredients from all possible fresh and dried plant matrices, such as leaves, flowers, wood, roots, and seeds. Additionally, the student is able to select the extraction method to enrich the class of active ingredients of interest through single-seat laboratory exercises.

Teaching methods

Theoretical lessons and single-seat laboratory exercises.

Given the types of activities and teaching methods adopted, attendance of this educational activity requires all students (including international students, e.g., ERASMUS) to complete workplace health and safety modules 1, 2 and 3.

You can consult the details of the Modules and the implementation methods on the course website, on the "Formazione obbligatoria salute e sicurezza" page of the "Studiare" section.

Assessment methods

The assessment begins with a PowerPoint presentation of a paper related to a laboratory experience chosen by the student. It continues with questions to verify the acquisition of the knowledge and skills defined by the course objectives.

Teaching tools

PowerPoint/PDF slides and analytical chemistry laboratory equipments.
