Secondary Metabolite Profiling

Secondary metabolite profiling refers to the analytical classification of non-essential plant compounds—including terpenes, flavonoids, and cannabinoids—that accumulate in cannabis tissues. Rather than describing a single aroma, this term encompasses the laboratory-based identification and quantification of volatile and non-volatile chemical signatures that collectively define a strain's aromatic and phytochemical fingerprint. Profiling data relies on techniques such as gas chromatography-mass spectrometry (GC-MS) and liquid chromatography to map compound ratios across cultivars. Breeders and researchers use profiling as an objective framework for strain differentiation, inheritance tracking, and selection of chemically consistent genetics across generations.

Secondary metabolite profiling enables breeders to select parent plants based on reproducible chemical markers rather than subjective aroma assessment alone. This data-driven approach supports the development of stable F1 hybrids and F2+ lines with predictable terpene and cannabinoid ratios across seed crops.
