Course objectives

Objectives of Pharmacognosy are to impart knowledges of those drugs of biological origin and their constituents that are of value for their therapeutic, profylactic and diagnostic use in the human and veterinary medicine.
Its scope includes the study of the physical, chemical, biochemical and biological properties of drugs, drug substances, or potential drugs or drug substances of natural origin as well as the search for new drugs from natural sources. Research problems in pharmacognosy include studies in the areas of phytochemistry, microbial chemistry, biosynthesis, biotransformation, chemotaxonomy, and other biological and chemical sciences.
Pharmacognosy represents a highly interdisciplinary science which is one of five major areas of pharmaceutical education.

Learning outcomes

The student must be able to microscopically and macroscopically identify selected drugs, know their main content substances, use, basic biosynthetic reactions, basal classes of secondary metabolites. Know the main plants used in the pharmacy. Chemical characteristics of secondary metabolites, basic knowledge of structure-activity relationships, basic knowledge of adverse effects and interactions.
