Citral Terpene Profiles

Citral is a monoterpene compound commonly found in cannabis strains with lemon, lime, and citrus-forward aromatic profiles. The molecule exists as two isomers—geranial and neral—which together create the characteristic bright, zesty character often tagged in cultivars descended from Lemon Haze, Super Lemon Haze, and Citral-dominant breeding lines. Citral concentrations are frequently reported in the 0.5–2% range across tested flower samples, though exact levels vary by cultivation environment and harvest timing. Breeders working in this category often select parent plants with elevated geranial and neral profiles to stabilize citrus aromatics across generations. The terpene is structurally related to limonene and myrcene, and cannabis chemotypes expressing high citral typically display rapid terpene volatilization during curing and storage.

Breeders targeting citrus-forward phenotypes routinely select for citral-dominant chemotypes by testing parent material and culling offspring that express competing terpene profiles. Citral stability under post-harvest conditions remains a key consideration in strain stabilization, as the volatile nature of this monoterpene requires careful drying and storage protocols to preserve the desired arom
