Study Notes

Pharmacognosy

  • The term "pharmacognosy" refers to the study of medicine derived from natural sources.

Crude Drugs

  • Crude drugs are the raw materials obtained from plants, animals, or minerals used in the production of medicines.
  • These raw materials are not processed or refined.
  • Crude drugs can be natural products like:
    • Plants
    • Animals
    • Minerals
  • Crude drugs are primarily used for:
    • Medicinal purposes
    • Pharmaceutical preparations
    • Dietary supplements
    • Cosmetics

Drugs From Plants

  • The study of drugs from plants includes aspects of:
    • Botany: the study of plants
    • Phytochemistry: the study of plant chemicals
    • Pharmacology: the study of how drugs interact with living organisms
    • Ethnobotany: the study of how plants are used in traditional medicine
    • Biotechnology: the use of living organisms to produce drugs

Natural Products and Crude Drugs

  • Natural Products: Substances that occur in nature, and can be extracted from plants, animals, or minerals.
  • Natural products used as crude drugs can be:
    • Alkaloids: nitrogen-containing compounds with pharmacological activity
    • Glycosides: compounds containing a sugar molecule attached to a non-sugar molecule
    • Tannins: plant polyphenols with astringent properties
    • Resins: complex mixtures of organic compounds with adhesive properties
    • Volatile Oils: fragrant compounds extracted from plants
    • Fixed Oils: non-volatile oils extracted from plants
    • Gums: plant polysaccharides with mucilaginous properties
  • Synthetic products are NOT natural products.
