Metabolite Profiling

Metabolite profiling refers to the systematic analysis and identification of small molecules—including cannabinoids, terpenes, flavonoids, and other secondary metabolites—produced by cannabis plants. This analytical approach maps the chemical fingerprint of a cultivar, documenting compound diversity and relative abundance across different tissue types and developmental stages. Metabolite profiling data has become foundational to modern cannabis breeding, enabling breeders to select parents with desired chemical traits and track consistency across generations. The practice relies on techniques such as gas chromatography–mass spectrometry (GC-MS), liquid chromatography–mass spectrometry (LC-MS), and high-performance liquid chromatography (HPLC) to quantify and characterize plant chemistry with precision. Understanding metabolite profiles helps distinguish between phenotypically similar pla

Breeders use metabolite profiling data to make informed crosses, selecting parents whose chemical profiles complement breeding goals—whether targeting specific terpene blends, cannabinoid ratios, or novel minor-compound expression. Profiling also helps stabilize F1 and subsequent generations by identifying which offspring express desired metabolite combinations, accelerating the development of sta
