Integrated course unit module: PLANT BIOLOGY - PHARMACOGNOSY

Learning objectives

Knowledge and understanding skills
1) To acquire the basic notions of pharmacognosy (source of active principles, technological processes, phytochemistry, classification of active principles)
2) To remember the botanical name of the plants
3) To acquire preliminary pharmacokinetic and pharmacodynamic notions for understanding the pharmacological activity of natural substances.
4) To know the pharmacological activity of the main natural molecules and their mechanisms of action
5) To Acquire ability in using the specific language of the discipline.

Knowledge and understanding applied skills
1) To apply the knowledge of the mechanisms of action of the natural molecules to define their pharmacological activity and use

Judgment autonomy
1) To evaluate the validity of a phytotherapy product in independent manner

Communicative Skills
1) Possess the ability to synthesize information and effectively communicate it to specialists and non-specialists.

Learning Skills
1) Develop skills and methodology that will allow you to study in a highly indipendent way.
2) Updating the knowledge through the consultation of scientific databases


There are not prerequisites. However, the following exams are highly recommended: Human anatomy/animal biology

Teaching methods

The lessons will be mainly frontal, but will be complemented by online bibliographic research in order to provide students with the ability to know reliable databases from which to obtain information onphytotherapy products.
The slides used to support lessons, as an integral part of the teaching material, will be uploaded weekly on the Elly platform.

Assessment methods and criteria

Oral examination, to be performed together with Plant Biology (as single exam).
Oral testing to be supported at the same time as the Plant Biology module (they are a single exam, both modules must be sufficient to overcome it).
Scale of assessment: 0-30
Weights and evaluation criteria:
1) Acquired knowledge (up to 14/30);
2) Ability to apply the acquired knowledge and to make connections between the covered topics (up to 10/30);
3) capacity to communicate concepts through the use of the specific language of the discipline (up to 6/30).
