Secondary Metabolite Profiling

Secondary metabolite profiling refers to the systematic analysis and documentation of non-essential chemical compounds produced by cannabis plants, including cannabinoids, terpenes, and flavonoids. Unlike primary metabolites required for basic plant function, secondary metabolites accumulate in resin glands and contribute to the plant's chemical signature. This classification framework enables breeders and researchers to categorize cannabis genetics by their complete chemical profile rather than single compounds alone. Profiling typically involves chromatographic techniques like HPLC or GC-MS to identify and quantify these compounds. Understanding secondary metabolite composition is foundational to cannabis genetics work, helping breeders predict offspring traits and maintain genetic records across generations.

Breeders use secondary metabolite profiling data to make informed selection decisions, identify unique chemical phenotypes within a line, and verify genetic stability across generations. This approach supports the documentation of strain genetics more precisely than phenotype observation alone, enabling more reproducible breeding programs.
