Secondary Compounds

Secondary compounds in cannabis refer to volatile and semi-volatile molecules produced beyond primary cannabinoids and terpenes—including flavonoids, phenolic compounds, and minor volatile organics. These constituents contribute to strain-specific aroma profiles and are often studied for their potential roles in plant defense and chemotaxonomy. Lineage records frequently report that secondary compound expression varies significantly across genotypes, even within closely related crosses. Breeders working in phytochemistry-focused programs use gas chromatography and mass spectrometry to identify and stabilize secondary compound signatures as breeding markers. Understanding secondary compound diversity is central to cannabis genetics classification and preservation of heirloom and landrace genetics.

Breeders selectively maintain secondary compound profiles to preserve strain identity and create novel aroma combinations through backcrossing and polyhybrid selection. Secondary compound stability across generations serves as a genetic fingerprint for strain verification and intellectual property tracking in licensed breeding programs.
