Medicinal & Aromatic Plants: Economic Impact & Export Potential
Role in National Economy
Medicinal and aromatic plants play a significant role in the national economy, with about 25% of current medications derived directly or indirectly from plant components. Examples include morphine, quinine, digoxin, and many others. Aromatic plants provide spices, medicines, and raw materials for essential industrial chemicals. India is a major producer of essential oils like ajwain, citronella, and eucalyptus.
Indian Scenario in Trading
Kerala leads in black pepper, cardamom, and ginger production, while Andhra Pradesh dominates turmeric and chili production. Spice exports have seen consistent growth, with pepper, in particular, experiencing a rise in both quantity and value.
Phytochemical Evaluation of Drugs
Phytochemicals are biologically active substances produced by plants and are the primary source of active ingredients in the pharmaceutical industry. They include phenolic compounds, terpenoids, alkaloids, and more. Phytochemical investigation involves extracting and characterizing these compounds from plant materials.
Types of Phytochemical Tests
There are two main types of phytochemical tests:
- Quantitative tests determine the purity or concentration of constituents.
- Qualitative tests identify different types of adulterants.
Common qualitative tests include those for alkaloids, glycosides, carbohydrates, proteins, and amino acids.
