Solvent Selectivity

Solvent selectivity refers to how different extraction solvents interact with and isolate specific terpene profiles from cannabis plant material. The choice of solvent—whether hydrocarbon, ethanol, CO2, or others—directly influences which volatile compounds are captured and in what concentrations. This selectivity occurs because terpenes vary in polarity and molecular weight, making some preferentially soluble in certain solvents while others remain in the plant matrix. Breeders and extractors document terpene retention rates across solvent types to understand and predict the aromatic and chemical character of final products. Understanding solvent selectivity is foundational for comparing extraction methods and for breeding programs focused on specific terpene stability.

Breeders working with extraction-focused lineages track how their cultivars' terpene profiles respond to different solvent systems. This data informs strain selection for commercial extraction pathways and helps predict consistency in downstream processing.
