Abstract
Origanum strobilaceum Mobayen & Ghahreman belongs to Lamiaceae. Thirty eight species of the genus were known so far which are categorized in 9 sections. The species is aromatic and its essential oil compositions are valuable. In this research, for the first time, the essential oil content and composition of O. strobilaceum was studied. The aerial parts of the plant were collected from janat rodbar in Mazandaran Province road at full flowering stage. After drying the plant materials, the essential oil was obtained by hydro-distillation method. Identification of essential oil constituents was done by using GC and GC/MS. The results showed 29 constituents in this oil that presented 97.3% of total oil. The main components of the oil were P-cymen (25%), E-caryophyllen (14.4%), thymol (9.6%), carvacrol (5.3%) and cumin aldehyde (5.1%). This oil had some similarities and differences with O. vulgare oil with high content of phenols, thymol and carvacrol as well as germacrene D and caryophyllene.
