Satureja khuzistanica Jamzad is a species native to Iran and is highly important in south western regions. It belongs to the Lamiaceae family which is widely used in various pharmaceutical, food, cosmetic and health industries. Quantitative comparison of the essential oil extracted from the flowering branches of S. khuzistanica shows that the amount of essential oil varies between 2.5 % and 3.7 %. Chemical analysis of essential oils revealed that the main and common constituents of essential oils are carvacrol (92.21 to 95.75%), γ-terpinene (0.37 to 1.93%), p-cymene (0.48 to 1.64%), β-bisabolene (0.64 to 0.83%), and myrcene (0.26 to 0.67%). The relative density of S. khuzistanica essential oil at 20 °C is from 0.953 to 0.987, and the refractive index of essential oil at 20 °C is from 1.5064 to 1.5147, the optical rotation of essential oil at 20 °C is from -1.00 to -1.40 degrees. If one volume of S. khuzistanica essential oil is mixed with 1.4 volume of 80% ethanol at a temperature of 20 °C, a clear liquid is obtained.
