Phytochemical Screening

Phytochemical screening refers to laboratory analysis techniques used to identify and quantify the chemical compounds present in cannabis plant material. These methods detect cannabinoids (THC, CBD, CBN, etc.), terpenes, flavonoids, and other secondary metabolites that distinguish one genetics line from another. Screening protocols typically employ chromatography, spectrometry, or immunoassay techniques to create a chemical fingerprint of a sample. Breeders and seed banks increasingly rely on phytochemical data to verify strain authenticity, track genetic stability across generations, and document the inheritance patterns of specific compound profiles. This practice has become foundational to modern breeding work, moving beyond phenotype observation alone.

Breeders use phytochemical screening to confirm that offspring express intended cannabinoid and terpene ratios, validate parent plant selection, and establish documented baselines for cultivar identity. This data supports selective breeding decisions and helps stabilize novel genetic combinations.
