Terpene Profiling Testing

Terpene profiling testing is a laboratory analytical method that identifies and quantifies volatile organic compounds in cannabis samples. Using techniques such as gas chromatography-mass spectrometry (GC-MS) or liquid chromatography, labs measure the concentration and diversity of terpenes present in a strain. This data helps breeders understand strain chemistry, verify genetic stability across generations, and document the aromatic and flavor compound profile. Profiling results typically report dozens of individual terpenes, revealing which compounds dominate ("primary terpenes") and which appear in trace amounts. Standardized testing protocols enable consistent comparison across seed lots and breeding lines, supporting transparent lineage documentation.

Breeders use profiling data to track terpene inheritance patterns, select parent plants with desired chemical profiles, and maintain consistency in commercial seed lines. This testing is foundational for understanding how cross-breeding affects volatile compound expression and for documenting the chemical signatures that distinguish strain families.
