Terpene Volatile Profiling

Terpene volatile profiling refers to the analytical characterization of aromatic compounds in cannabis through chromatographic and spectrometric methods. Breeders and researchers use gas chromatography-mass spectrometry (GC-MS) and liquid chromatography techniques to identify and quantify terpene concentrations across cultivars. This practice emerged as breeding programs sought objective data beyond sensory evaluation to understand aroma complexity and chemical consistency. Volatile profiling data helps establish genetic signatures within strain families and tracks how environmental factors influence terpene expression. Understanding these profiles supports informed breeding decisions and enables documentation of chemotype variation across populations.

Breeders use volatile profiling data to select parents with desired terpene expressions and to stabilize chemotypes across generations. This analytical approach allows systematic comparison of volatile compounds across related lineages, supporting the development of cultivars with consistent aromatic and chemical characteristics.
