Background: The genus Stachys (Lamiaceae) is distributed in mild regions of the Mediterranean and south-west Asia. About 270 Stachys species are reported 34 of them are found in Iran of which 13 are endemic. Several Stachys species are used in Iranian folk medicine as medicinal plants. There is no report on Stachys athorecalyx essential oil analysis previousely. Objective: Investigation on essential oil constituents of Stachys athorecalyx collected from Arasbaran protected area Method: in this study, Stachys athorecalyx has been collected from the Arasbaran protected areas shade dried and the essential oil extracted by means of steam distillation and analyzed with GC/MS. Results: Thirty six compounds representing 98.1% of total oil were identified in the oil of Stachys athorecalyx. Spathulenol (22.1%) was the major compounds. Oxygenated compounds were predominant (71.2%). Eighteen monoterpenes (47.9%), thirteen sesquiterpenes (42.9%) and two aromatic compounds (1.6%) were founded. Conclusion: according to our investigation’s results and considering previousely reports on other Stachys species’ essential oil compounds, there is good similarity between essential oil compounds of this species and other reported species in this genus.
