(Labiatae), collected in 3 stages (pre-flowering, flowering and post-flowering) from plants grown in the Fars province of Iran were obtained by steam distillation. The chemical composition of the oils were analyzed by GC-MS. Analysis of the chemical profile of the isolated oils revealed the presence of >80 compounds, mainly sesquiterpene hydrocarbons, oxygenated monoterpenes and sesquiterpenes. They contained α-terpinyl acetate, α-cadinene, 1,4-cadinadiene, linalool and cadinol. Average yield was 1%. The studied essential oils showed good antioxidant activities as calculated by 3 in vitro assays: DPPH radical scavenging, Ferric Reducing Power Assay (FRAP) and Reducing Power (RP).} }
