Hydrocarbon Extraction

Hydrocarbon extraction refers to cannabis processing methods using volatile solvents—primarily butane, propane, or hexane—to dissolve cannabinoids and terpenes from plant material. The resulting concentrate is then purged of residual solvent through heat and/or vacuum to produce products ranging from shatter and budder to live resin. This classification encompasses closed-loop systems designed to contain solvent vapors and recover unreacted liquid, as well as open-blasting techniques, both carrying distinct safety and regulatory profiles. Hydrocarbon methods are valued in breeding research for their ability to preserve volatile terpene profiles during extraction, making them relevant for genetic and chemotype documentation. Proper licensing, equipment certification, and safety protocols are required in regulated jurisdictions.

Breeders and seed developers use hydrocarbon extraction data to analyze terpene retention and cannabinoid profiles across genetics, helping establish chemotype baselines for strain documentation. The method's sensitivity to volatile compounds makes it useful for comparing phenotypic variation within a line.
