Study Notes
Volatile Oils
Essential Oils
- Highly concentrated plant extracts containing aromatic compounds
- Obtained through distillation or solvent extraction
- Used in aromatherapy, perfumery, and pharmaceutical industries
Aromatic Compounds
- Responsible for the fragrance and pharmacological effects of volatile oils
- Include terpenes, terpenoids, and phenolic compounds
- Can be classified into monoterpenes, sesquiterpenes, and diterpenes based on molecular structure
Pharmacological Effects
- Anti-inflammatory, antimicrobial, and antioxidant properties
- Used to treat various health conditions, such as anxiety, insomnia, and pain
- Can interact with medications and have adverse effects in certain individuals
Plant Sources
- Obtained from various plant parts, including leaves, flowers, roots, and seeds
- Examples of plants used to produce volatile oils: lavender, peppermint, eucalyptus, and tea tree
Distillation Methods
- Steam distillation: most common method, uses steam to release aromatic compounds
- Solvent extraction: uses a solvent to dissolve and extract aromatic compounds
- Cold pressing: used for citrus fruits, involves squeezing the peel to release oil
- Enfleurage: ancient method, uses animal fat to absorb and extract aromatic compounds
