Phytochemical Analysis

Phytochemical analysis refers to the laboratory examination of plant-derived compounds in cannabis, identifying and quantifying cannabinoids, terpenes, flavonoids, and other secondary metabolites. This analytical approach has become foundational in cannabis breeding and cultivation research, allowing growers and breeders to document the chemical profiles of parent plants and resulting offspring. Modern phytochemical analysis typically employs chromatography and spectrometry techniques (HPLC, GC-MS, LC-MS) to separate and identify individual compounds. Understanding a strain's complete phytochemical composition—beyond THC and CBD alone—helps breeders select for desired genetic traits and predict phenotypic stability across generations. Accurate phytochemical data supports breeding programs focused on terpene profiles, minor cannabinoid expression, and plant chemotype consistency.

Breeders use phytochemical analysis to establish baseline profiles for parent lines, track inheritance patterns of minor cannabinoids and terpenes, and validate F1 or F2 generation chemotypes. This data informs selective breeding strategies and helps stabilize desired chemical expressions across multiple plant generations.
