Pharmacognosy Overview Quiz

Definition

• Pharmacognosy is the study of natural products derived from plants, animals, and minerals for medicinal use.

Key Areas of Focus

1. Source Identification

   • Identification of medicinal plants and their active compounds.
   • Study of traditional medicine systems.

2. Extraction Techniques

   • Methods to isolate bioactive compounds (e.g., distillation, solvent extraction, maceration).

3. Characterization

   • Analyzing the chemical structure and properties of natural products.
   • Techniques include chromatography, spectroscopy, and mass spectrometry.

4. Bioactivity Assessment

   • Evaluating the pharmacological effects of natural compounds.
   • Tests for antimicrobial, anti-inflammatory, analgesic, and other biological activities.

5. Quality Control

   • Ensuring the purity, potency, and safety of herbal medicines.
   • Standards include identification of key markers, contaminants, and adulterants.

Importance

• Provides a foundation for drug discovery and development.
• Offers insights into traditional remedies and their therapeutic potentials.
• Contributes to the understanding of plant-based pharmaceuticals and their mechanisms of action.

Applications
