Although not mandatory, a good knowledge of plant biology and organic chemistry is strongly advised.
The student will be asked to demonstrate a thorough comprehension regarding the constitutive topics covered in all five training objectives. Students will perform two tests by using the e-learning platform. Precisely, one is intermediate, i.e. scheduled during the course, and address the topics of training objectives 1, 2 and 3; the second test coincides with the official date of the first exam session and addresses the training objectives 4, 5 and 6. Tests consist of multiple-choice questions, corresponding tests, written text, figures and tables interpretation. The final score is the mean of the two evaluation tests. The use of the e-learning platform also makes it possible to assess the student's progressive ability to use self-assessment systems.
In subsequent exam sessions the verification will take place in the same way, considering a longer time available being the two tests performed on the same day.
The present course is in the second or third year, depending on the curriculum chosen, contributing to a training program on Botany for biotechnologies, which starts from plant biology and ends with plant biotechnology. It is in line with the traditional course of Pharmaceutical Botany, updated in both the systematic background according to the recent advances from the Angiosperm Phylogeny Group panel, and the most important plant-based pharmaceutical forms. Factors affecting the production of active compounds by the plant are analysed in detail. Links among Pharmacognosy, Organic Chemistry, Botany, Systematic Botany and Biology are elucidated as well.
Students are encouraged to acquire greater and conscious independence in self-evaluation of their work and their ability to learn using the e-learning platform.
The following learning outcomes are expected:
1. to acquire the basic knowledge on the main metabolic pathways of secondary metabolites in plant cell.
2. to acquire the basic and advanced knowledge on the chemical structure of the macro-categories of sec-ondary metabolites.
3. to acquire the basic knowledge on the main plant secondary metabolites with pharmacological applica-tions.
4. to understand the environmental factors affecting the secondary metabolites production
5. Phytotherapy
6. to acquire the basic knowledge on Systematic Botany
Moreover, students must show inclination towards a professional approach to their work.
Lectures (5.5 cfu, 44 hours)
The secondary metabolism in plants (14h, training objective 1 e 2)
• Recall of plant morphology and physiology: secretory tissues
• Secondary metabolism and the main biosynthetic pathways of secondary metabolites
• Chemical structure of the macro-categories of secondary metabolites:
- Phenolic compounds (Flavonoids, Tannins, Lignins, Lignans, Coumarins, Chinons, Cannabinoids)
- Terpenoids (essential oils, Steroids, Iridoids, Saponines, Resines, Rubbers, cardiac glycosides)
- Nitrogen compounds (Alcaloids, Glucosinolates, non-proteic aminoacids, cianogenic glycosides)
Bioactive plant secondary metabolites of pharmacological interest (8h, training objective 3)
Location of the secretory tissues and related extractive methods
Environmental factors (6h, training objective 4)
Endogenous and exogenous factors affecting bioactive compounds production
Phytotherapy (6h, training objective 5)
notes on extractive methods and type of products of phytotherapy
Systematic Botany: definition and aims. Classification criteria. Taxonomy (6h, training objective 6)
- Algae
- Fungi
- Bryophytes
- Pteridophytes
- Gymnosperms
- Angiosperms
Laboratory (0,5 cfu, 8h)
Extraction method of:
- a phenolic compound from clove (Syzygium aromaticum): eugenol
- essentials from Salvia officinalis and Melissa officinalis
- limonene from rind fruit of Rutaceae and GC-MS analysis
Analytical guides for species identification and classification

• Badal McCreath SB and Delgoda R. Pharmacognosy, Fundamentals, Applications and Strategies. Academic Press, Ed 2017
The course consists of lectures (5,5 CFU) and laboratory (0,5 CFU).
The course consists of of 44h of frontal lessons and 8h of laboratory activities, totaling 52 h (6 CFU). The addressed topics will be integrated by presentation of picture slides, graphics, diagrams and videos useful to clarify the concepts.
The aim of the course is also to stimulate the student's self-learning skills by stimulating, independently from the teacher, the search in the web for further information on specific aspects of the course.
For laboratory activities, students are divided in small groups and are assigned a location for the self-conduct experiment. The access to the rooms is allowed only if equipped with white coat. The presence of the lecturer and one or more assistants will be guaranteed. Lab attendance is mandatory, and absence should not exceed 25% (2h) of the laboratory planned program.
