Preparation Process: **Preparation of Peppermint Oil:** Peppermint oil is obtained through steam distillation of the fresh or partially dried aerial parts (leaves and stems) of *Mentha piperita* L. The process involves: 1. **Harvesting:** Collect peppermint leaves at peak oil content, typically before flowering. 2. **Loading:** Place the plant material in a distillation chamber. 3. **Steam Distillation:** Pass steam through the plant material, vaporizing the volatile oils. 4. **Condensation:** Cool the vapor in a condenser to separate the oil-water mixture. 5. **Separation:** Use a Florentine flask to isolate the oil from the hydrosol. 6. **Drying:** Remove residual moisture using anhydrous sodium sulfate. 7. **Storage:** Store in airtight, dark glass containers to prevent oxidation. Yield: ~0.5–1.5% (w/w).
