Solvent Extraction Methods

Solvent extraction methods are laboratory techniques used to isolate cannabinoids, terpenes, and other plant compounds from cannabis biomass. Common solvents include ethanol, butane, propane, CO₂, and hexane, each producing different end products—from concentrates to distillates—based on solubility profiles and processing temperature. These methods are distinct from plant aroma itself; rather, they're tools breeders and processors use to study volatile compound profiles and create standardized extracts for research. Understanding solvent extraction is relevant to genetics work because it reveals the actual terpene and cannabinoid composition of a strain, independent of sensory perception. Different extraction methods can highlight or suppress certain volatile compounds, affecting what aroma profiles are detected in final products.

Breeders use solvent extraction data—particularly chromatography analysis—to identify and select for specific terpene combinations and cannabinoid ratios in parent plants. Extraction techniques help document phenotypic variation within a strain family and guide selection decisions for consistent aroma and potency profiles across generations.
