Terpene Profiling Methods

Terpene profiling methods are laboratory and analytical techniques used to identify and quantify volatile aromatic compounds in cannabis plant material. Common approaches include gas chromatography-mass spectrometry (GC-MS), liquid chromatography (LC), and headspace analysis, each offering different resolution levels and compound detection ranges. Breeders and researchers employ these methods to document aromatic signatures, track inherited terpene expression across generations, and establish baseline profiles for strain families. Profiling data helps distinguish phenotypic variation within a genotype and supports selective breeding for consistent aromatic characteristics. Standardized profiling has become increasingly important for lineage documentation and quality reference purposes in the breeding community.

Breeders use terpene profiling data to map which aromatic traits breed true, identify recessive terpene expressions, and select parent plants that consistently produce desired volatile profiles across offspring. Profiling results inform crossing strategies and help breeders recognize which lineages carry specific terpene combinations worth preserving or combining with other genetics.
