Study Notes
Soxhlet Extraction Overview
- Soxhlet extraction utilizes a continuous hot extraction method ideal for compounds with low solubility in a given solvent.
- The process is effective in isolating desired substances while leaving insoluble impurities behind.
Extraction Definition and Purpose
- Extraction is a technique to separate active medicinal components from plants using selective solvents.
- It employs standard procedures to enhance the purity and effectiveness of extracted compounds.
Factors Influencing Extraction Methods
- Length of Extraction Period: The duration of extraction impacts the yield and efficiency of the process.
- Solvent Used: Different solvents can influence the solubility and extraction efficiency of target compounds.
- pH of Solvent: The acidity or alkalinity can affect the solubility and stability of the compounds being extracted.
- Temperature: Higher temperatures can increase solubility and extraction rates but may also degrade sensitive compounds.
