Researchers analyzed essential oils from ten populations of rosemary (Rosmarinus officinalis) in the Balkan Peninsula using GC/FID and GC/MS techniques.
The main components identified were 1,8-cineole, camphor, α-pinene, and borneol, classifying the oils into distinct types based on these constituents.
Analysis showed that temperature of the habitat was the key factor influencing the chemical composition of the oils, although some constituents were not linked to specific bioclimatic factors while others had notable correlations with certain abiotic factors.
