Terpene Profiling And Testing

Terpene profiling and testing refers to the analytical identification and quantification of volatile aromatic compounds present in cannabis flower, concentrate, and plant tissue. Modern laboratories use gas chromatography (GC), liquid chromatography (LC), and mass spectrometry (MS) to detect individual terpenes such as limonene, myrcene, pinene, and caryophyllene at varying concentrations. Breeders and researchers employ terpene profiling to document strain lineages, track genetic consistency across generations, and correlate aromatic signatures with parent plants. Testing data has become standard documentation in cannabis genetics work, allowing accurate description of cultivar characteristics independent of subjective sensory assessment. Terpene profiles vary significantly between phenotypes of the same strain and can shift based on cultivation conditions, harvest timing, and post-harv

Breeders use terpene profiling data to verify genetic stability in line breeding, identify rare or desirable terpene combinations within a genetic family, and maintain accurate strain records across commercial seed and clone production. Consistent terpene signatures help distinguish F1 hybrids from open-pollinated seed stock and validate parent plant genetics in controlled crosses.
