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.
