    Study Notes

    Natural Products and Phytochemicals

    • Natural products are derived from plants, animals, or microorganisms and have therapeutic potential.
    • Phytochemicals are bioactive compounds found in plants that contribute to their color, flavor, and disease resistance.

    Classification of Phytochemicals

    • Primary Metabolites: Essential for plant growth and development (e.g., carbohydrates, proteins, lipids).
    • Secondary Metabolites: Non-essential compounds with health benefits (e.g., alkaloids, flavonoids, terpenoids).
    • Phenolic Compounds: Known for antioxidant properties and include flavonoids, phenolic acids, and tannins.
    • Alkaloids: Nitrogen-containing compounds with medicinal uses, such as morphine and caffeine.
    • Terpenoids: Large class of compounds with diverse roles, including essential oils that have therapeutic effects.

    Advantages of Phytochemicals

    • Antioxidant properties help in combating oxidative stress and prevent chronic diseases.
    • Anti-inflammatory effects support immune function and reduce the risk of inflammation-related conditions.
    • Potential antibacterial, antiviral, and antifungal properties contribute to disease prevention and treatment.
    • May enhance cardiovascular health by improving cholesterol levels and promoting healthy blood pressure.

    Extraction Methods

    • Maceration: Soaking plant material in solvent to extract phytochemicals; commonly performed at room temperature.
    • Reflux Extraction: Continuous boiling and condensation of solvent, allowing for efficient extraction of compounds.
    • Soxhlet Extraction: Uses a specialized apparatus to repeatedly wash the plant material with solvent for thorough extraction.
    • Percolation: Involves the use of gravity or pressure to move solvent through moist plant material for effective extraction.
    • Pressurized Liquid Extraction: Uses high pressure and temperature to enhance solubility and extraction efficiency.
    • Decoction: Boiling plant materials in water to extract water-soluble compounds, commonly used with tougher plant parts.
    • Microwave-Assisted Extraction: Utilizes microwave energy to heat solvents and plant materials, improving extraction efficiency and speed.
    • Enzyme Assisted Extraction: Involves enzymes to break down cell walls, enhancing the release of phytochemicals for more effective extraction.
