Extraction techniques<br />
Obtaining extracts from <strong>medicinal</strong> <strong>plants</strong><br />
Plant extracts are pharmaceutical/phyto pharmaceutical fluids, soft or dry,<br />
obtained by solvent extraction of different plant products.<br />
1. Discontinuous processes<br />
• Maceration cold (17-22°C)<br />
warm (40-60°C)<br />
•Percolation<br />
•Soxhlet extraction<br />
•Infusion<br />
•Decoction<br />
•Fermented alcoholic extraction<br />
•Continuous extraction with organic<br />
solvents<br />
•Accelerated solvent extraction(ASE)<br />
•Microwave assisted extraction(MAE)<br />
•Ultrasound-assisted extraction(UAE)<br />
•Supercritical fluid exctraction(SCF)<br />
2. Continuous processes: continuous extraction with organic solvents,<br />
continuous precolation, Soxhlet extraction.
