Volatile Terpene Profiling

Volatile terpene profiling refers to the analytical identification and quantification of terpenes that readily evaporate at room temperature or during standard extraction and storage. These compounds—including limonene, pinene, and myrcene—represent the most transient fraction of a plant's aromatic profile and require specialized chromatography techniques (GC-MS, headspace analysis) to measure accurately. Profiling volatile terpenes is essential for understanding cultivar authenticity, since these compounds degrade rapidly under heat, light, and oxidative conditions. Breeders and researchers use volatile profiling to document baseline terpene expression across seedlines and to track stability during seed storage or plant development. This data becomes foundational for establishing strain identity and predicting how a cultivar's aroma will change post-harvest.

Breeders rely on volatile terpene profiling to select parent plants with desired aromatic characteristics and to verify that progeny maintain terpene expression across generations. Volatile profiles also inform storage and preservation protocols—cultivars showing high volatility require different handling than those dominated by sesquiterpenes.
