Secondary Volatile Compounds

Secondary volatile compounds (SVCs) encompass minor terpenes, sesquiterpenes, and other aromatic molecules present in cannabis at lower concentrations than primary terpenes like myrcene or limonene. These compounds—including compounds like caryophyllene oxide, humulene, and various esters—contribute to strain-specific aromatic profiles and are of growing interest in breeding programs. While primary terpenes typically dominate analytical profiles, SVCs can modulate overall sensory character and are increasingly tracked by cultivators and breeders working to develop distinctive phenotypes. Understanding SVC composition requires advanced chromatography methods, making this category less standardized in seed descriptions than major terpene profiles. Lineage records and terpene testing increasingly reveal that SVC ratios vary significantly between cultivars, even within established strain fam

Breeders selecting for specific aromatic or sensory profiles often monitor SVC ratios alongside dominant terpenes, as these compounds can define subtle varietal distinctions. Stabilizing or amplifying particular minor terpene combinations requires multi-generational selection and careful environmental control during testing.
