SOXHLET EXTRACTION 1.0 SCOPE AND APPLICATION 1.1 Method 3540 is a procedure for extracting nonvolatile and semivolatile organic compounds from solids such as soils, sludges, and wastes. The S oxhlet extraction process ensures intimate contact of the sample matrix with the extraction solvent. The basic principle is to grind the plant material (dry or wet) finer, which increases the surface area for extraction thereby increasing the rate of extraction. Earlier studies reported that solvent to sample ratio of 10:1 (v/w) solvent to dry weight ratio has been used as ideal Solvents used for active component extraction are: Water,
