    Welcome to Pharmacognosy II Class


  • Course Description

    Pharmacognosy is the study of plants or other natural sources as a possible source of drugs. The American Society of Pharmacognosy defines pharmacognosy as "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"So, this subject introduces gross phytochemistry and pharmaceutical as well as pharmacological uses of different plant constituents along with considerations of some important local and foreign drugs of each group.

    • Course Objectives

      Upon successful completion of the course, the students will be able to:

      1.      Recognize the primary knowledge of the general methods of extraction, isolation, purification, identity and assay of different chemical classes of bioactive natural compounds.

      2.      Describe the chemical classification, methods of extraction, isolation, physicochemical properties, tests for identity, assay and uses of selected natural compounds.

      3.      Clarify the pharmacological activity, toxicity and uses of the selected natural compounds.

      4.      Discover the presence or absence of active constituents in a drug and to determine the number of constituents in a plant.
