Steps for Plant Chemical Extraction
Selection & Preparation: Choose fresh/dried plant material (leaves, roots, etc.). Dry and grind it to increase surface area.
Extraction Method:
Maceration: Soak plant material in solvent (e.g., ethanol, water) for days, then filter.
Soxhlet Extraction: Continuous solvent cycling for efficient lipid/alkaloid extraction.
Steam Distillation: For volatile oils (e.g., lavender). Steam vaporizes compounds, which condense.
Cold Pressing: Mechanical pressing for citrus oils.
Solvent Choice: Polar solvents (water, methanol) extract polar compounds (flavonoids); non-polar (hexane) for oils.
Concentration: Use rotary evaporation or low-heat drying to remove solvents, leaving crude extract.
Purification: Techniques like chromatography (TLC, HPLC) or crystallization isolate specific compounds.
Analysis: Confirm purity/structure via spectroscopy (UV, NMR) or mass spectrometry.
Key Considerations
Safety: Use gloves, fume hoods; avoid toxic solvents.
Yield Optimization: Adjust solvent ratio, temperature, time.
Sustainability: Reuse solvents; prefer eco-friendly methods.
Example: Caffeine from tea leaves via Soxhlet extraction with ethanol.
