Learning Goals
The aim of this unit is to provide the basic knowledge of fundamental concepts and principles of Pharmacognosy about the chemical nature of secondary metabolites with medicinal interest, its effects, mechanisms of action, therapeutic applications and regulation of their use and applications. Students should develop competences to understanding the integrative concepts, processes and methods to access the knowledge and to solve practical problems relating to the analysis and safe use of natural products as well as to develop abilities to select and apply knowledge in the formulation of hypotheses, experimental design, and capacities to obtain and interpret experimental data in the field of pharmacognosy.
Contents
Pharmacognosy: general concepts, historical development and its relationship with other sciences;
Drugs and medicines of natural origin; Ethnopharmacology.
Products of primary and secondary metabolism, with medicinal or pharmaceutical interest.
Main secondary metabolites with medicinal interest: phenolic compounds (phenolic acids, flavonoids, tannins, anthraquinones and coumarins), alkaloids, terpenoids and saponins.
Mechanisms of action and toxicity of drugs of natural origin;
Research of new drugs of natural origin, its efficacy and safety;
Some of common therapeutic uses of drugs and drugs of plant origin and their interactions
Community legislation: The status of herbal medicines.
Phytochemical screening, antioxidant properties of medicinal plants.

Teaching Methods
The programmatic contents are interactive and supported by study material and recommended bibliography. Theoretical classes are plenary, with exposition of scientific contents and illustration of examples that concretize these concepts and encouraging research of information, autonomous work and the development a critical attitude and scientific rigor. Practical laboratorial classes include experimental procedures and resolution of applied problems and aims to promote the participation of the student on the execution of experimental works, interpretation of results, as well as to carry out a research work on a topic in the field of pharmacognosy.
The laboratorial component (NPL) is evaluated continuously, based on attendance, treatment and interpretation of results and in the presentation of the research work.
The theoretical component (NT) can be assessed through 2 written tests or by a final exam.
The final grade will be calculated as follows: NF = 0.4 * NPL + 0.6 * NT.
