Volatile Oils from Medicinal Plants

Definition
Volatile oils, also known as essential oils,
are concentrated hydrophobic liquids
containing volatile aroma compounds from
plants. They are extracted from various
parts of medicinal plants, including leaves,
flowers, seeds, and bark.

1. Extraction Methods
- Steam Distillation: The most common
method, where steam is passed through
plant material to vaporize the oil, which is
then condensed back into liquid.
- Cold Pressing: Primarily used for citrus oils,
where the peel is mechanically pressed to
release oil.
- Solvent Extraction: Uses solvents to
dissolve the oil, followed by evaporation to
leave behind the essential oil.

2. Composition
- Terpenes: The primary components,
responsible for fragrance and therapeutic
properties (e.g., limonene, pinene).
- Phenolics: Contribute to the antimicrobial
and antioxidant properties.
- Aldehydes and Esters Provide distinct
scents and have various biological activities.

3. Therapeutic Uses
- Antimicrobial: Many essential oils exhibit
antibacterial and antifungal properties (e.g.,
tea tree oil).
- Anti-inflammatory: Oils like eucalyptus
and lavender can help reduce inflammation.
- Aromatherapy Used for relaxation, stress
relief, and mood enhancement (e.g.,
chamomile, bergamot).

4. Applications
