Plant Volatile Profiling

Plant Volatile Profiling is the analytical classification and mapping of chemical compounds released by cannabis plants during growth, flowering, and post-harvest processing. These volatile organic compounds (VOCs)—including terpenes, esters, alcohols, and sulfur compounds—create the distinctive aromatic signatures associated with different cultivars and phenotypes. Profiling involves gas chromatography (GC), mass spectrometry (GC-MS), or similar instrumental methods to identify and quantify volatile emissions under controlled conditions. This classification system helps breeders document chemical consistency, differentiate cultivar lineages, and understand how environmental factors influence aromatic expression. Volatile profiles serve as objective markers for phenotype selection and cultivar authentication in breeding programs.

Breeders use volatile profiling data to select parent plants with stable, reproducible aromatic phenotypes and to track trait inheritance across generations. Profiling also helps identify undesirable off-flavor volatiles and supports the development of cultivars with predictable sensory characteristics for commercial and research applications.
