| | Procedure | Best For | | :--- | :--- | :--- | | Maceration | Plant material is soaked in a solvent at room temperature in a closed container for a set period. | Heat-sensitive compounds and delicate tissues. | | Percolation | Solvent is continuously passed through a column of the plant material. | Higher extraction efficiency and yields. | | Infusion & Decoction | Infusion: Material is soaked in hot or boiling water (like making tea). Decoction: Material is boiled in water for a specified time. | Water-soluble compounds from both soft (infusion) and hard (decoction) plant materials. | | Soxhlet Extraction | A hot solvent is continuously cycled through the plant material in a specialized apparatus. | Efficient for extracting with a single, appropriate solvent. | | Supercritical Fluid Extraction | Uses a supercritical fluid (most commonly CO₂) as the solvent for extraction. | Thermally labile compounds, high purity, and is an environmentally friendly "green" method. |
