Volatile Compound Analysis

Volatile Compound Analysis (VCA) refers to the laboratory methodology used to identify and quantify aromatic and flavor molecules in cannabis plant material. Rather than a single terpene or cannabinoid, VCA encompasses gas chromatography, mass spectrometry, and liquid chromatography techniques that reveal the complete chemical profile of a sample. Breeders and researchers use VCA to document which volatile compounds—including terpenes like myrcene, limonene, and pinene—are expressed in specific cultivars and crosses. This data helps establish lineage records, predict stability in offspring, and standardize strain descriptions across seed banks. VCA results inform selective breeding programs by identifying which parent plants consistently produce desired aromatic signatures.

Breeders rely on VCA data to track volatile compound inheritance patterns across generations and validate that F1, F2, and stabilized lines maintain their chemical profiles. Detailed VCA reports also allow seed producers to authenticate cultivars and document regional or phenotypic variation within strain families.
