Butane Extraction

Butane extraction is a solvent-based separation technique commonly used to isolate cannabinoids and terpenes from cannabis plant material. The process uses liquid butane—typically n-butane or isobutane—to dissolve target compounds, which are then recovered as the solvent evaporates. This classification describes extraction methodology rather than plant genetics, though the starting material's cannabinoid and terpene profile significantly influences final product composition. Butane hash oil (BHO), shatter, and wax are among the concentrate forms associated with this extraction route. The technique requires specialized equipment and safety protocols due to butane's flammability and volatility.

Breeders focused on concentrate production often select for lineages with high cannabinoid density and robust terpene profiles, since extraction efficiency depends on source material quality. Strains bred for terpene retention and cannabinoid expression are particularly valued in breeding programs targeting solvent-extraction workflows.
