Salvia santolinifolia Boiss. is a perennial aromatic plant from Lamiaceae family that grows wild in Iran. In the current study, the aerial parts of this plant were collected at full flowering stage from four habitats in Hormozgan province including Abmah, Ghotbabad, Dorahi-Meymand and Sirmand in 2018. After confirmation of scientific names of the plants by Herbarium of Agricultural Research, Education and Extension Organization of Hormozgan province, the plant materials were dried at shade and at room temperature. The essential oils were obtained by hydro-distillation, the yields were calculated based on dry weight and the oils were analyzed by GC and GC/MS. Results showed that maximum and minimum essential oil contents (w/w%) obtained from Ghotbabad (0.93%) and Abmah (0.65%) ecotypes, respectively. According to ecotypes, thirty-six components, representing 99.6 - 99.9% of the total components, were identified. α-Pinene, humulene epoxide, limonene, camphene, α-terpineol, myrcene and α-cadinol were the major compounds. Monoterpene hydrocarbons were the main group of constituents in all samples (69.3- 80.5%). The chemical variation among ecotypes according to their geographical and bioclimatic distribution could be considered for in situ and ex situ conservation and domestication of the plants.
