Gc Ms Phytochemistry

GC-MS (Gas Chromatography-Mass Spectrometry) phytochemistry represents the analytical framework breeders and researchers use to identify and quantify volatile and semi-volatile compounds in cannabis plant material. This family of analytical approaches catalogs cannabinoids, terpenes, and other secondary metabolites at the molecular level, providing objective data on strain composition. GC-MS methodology has become foundational in cannabis breeding programs seeking reproducible, measurable chemical profiles across generations. The technique separates compounds by volatility and mass, enabling precise identification of terpene ratios, cannabinoid percentages, and trace chemical markers that distinguish lineages.

Breeders use GC-MS data to select parent plants with target terpene or cannabinoid profiles, track chemical stability across F1-F∞ generations, and verify seed-to-harvest consistency. This analytical rigor supports phenotype documentation and helps establish reliable strain records in formal breeding programs.
