    Study Notes

    PharmDD Program (2023/2024)

    Introduction to Pharmacognosy

    • Students will acquire knowledge about cytology, physiology, and taxonomy of medicinal leafy plants, dusting powders, and preparation of natural products derived drugs.
    • The course will introduce students to different classes of secondary metabolites and pharmacologically active substances in certain official medicinal plants.

    Definition of Pharmacognosy

    • Pharmacognosy is a branch of pharmacy that deals with the study of medicines from natural sources (plant and animal) and their uses as medicaments from ancient times to present day.
    • It involves the study of structural, physical, chemical, and biochemical characters of natural drugs of plant and animal origin.

    Scope of Pharmacognosy

    • Pharmacognosy is a multidisciplinary subject that requires knowledge of botany, ethnobotany, phytochemistry, microbiology, pharmacology, pharmaceutics, etc.
    • It involves the studies of plants, animals, and other natural sources that yield crude drugs and drug substances, including their taxonomic identity, chemical, physical, and biological properties.

    Pharmacognosists' Role

    • Pharmacognosists isolate and characterize active constituents, evaluate the pharmacology of crude extracts and active constituents, and evaluate the quality of natural medicines.

    Medicinal Plants

    • Medicinal plants refer to the use of plant parts (seeds, berries, roots, leaves, bark, or flowers) for medicinal purposes.
    • Many species of plants contain substances of medicinal value that have yet to be discovered.

    Classification of Plants

    • Kingdom Plantae consists of over 325,000 species of plants with different characteristics and sizes.
    • Classification of plants is based on water requirements, habitat or environmental location, life duration, and natural system of classification.

    Classification Based on Habit of Body Appearance

    • Trees: woody plants with a single usually elongated stem.
    • Shrubs: low, usually several stemmed woody plants.
    • Herbs: plants with soft or succulent stem.

    Vascular Plants

    • Vascular plants with seed are classified into different groups.
