Abstract
The essential oils obtained from the flowering tops of Rosmarinus officinalis L. collected in two different stations with different microclimatic conditions are compared. Some significant differences were observed in the qualitative and quantitative compositions, mainly for α-pinene (8.9–15.4%), camphor (1.4–14.7%) and borneol (2.0–6.8%). The 1,8-cineole content remained stable at 53.7–58.6%.
