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.
