Whereas solvent-based extraction methods involve chemical dissolution, solventless extraction is essentially a mechanical separation process. One method is based on one-step in situ extraction/cleanup using accelerated solvent extraction (ASE) in which a mixture of copper, deactivated alumina and silica gel were added directly to the ASE cell along with sample; the second technique is based on dispersive solid phase extraction (dSPE) using alumina/silica for cleanup of biota samples to augment conventional ASE extraction combined . No harmful solvent residue. The extraction is repeated two to three times, or perhaps more times if the compound has a low partition coefficient in the organic solvent. The boiling point of the solvent should be low enough ( well below the melting point of the solute) such . Separation of aqueous and organic phase after extraction. Ethanol extraction is conducted by soaking raw cannabis in ethanol to pull trichomes into the solvent. This is an extraction method that involves the use of moderate heat during extraction process. 2)patrtion chromatography.
