Abstract Salvia leriifolia Benth is a perennial herbaceous plant and belongs to the Lamiaceae family; distributes among dry and warm regions in Iran. In the present study, the chemical compositions and antibacterial activity of essential oils from aerial parts of S. leriifolia collected from six natural habitats in North-East of Iran have been investigated. The essential oils were obtained by the hydrodistillation method by using a Clevenger type apparatus. The chemical composition of oils has been analyzed with GC/FID and GC/MS methods. The highest yield of oil was recorded from Kalateh-ye Hizomi (0.74 %) and the lowest amount obtained for Torbat-e Heydarieh sample (0.17 %). The major compounds characterized in oils were shyobunol (1.8-22.4 %), 1,8-cineole (6.2-14.1 %), β-pinene (5.3-13.1 %) and α-pinene (1.0-5.1 %). The highest antibacterial activity against Staphylococcus aureus detected from Kalateh-ye Hizomi (MIC=0.47 mg/mL) and lowest activity reported from Marus (MIC=1.87 mg/mL).

伊朗丹参种群地上部分精油的组成和抗菌活性

摘要 丹参为唇形科多年生草本植物；分布于伊朗干热地区。在本研究中，研究了从伊朗东北部六个自然栖息地收集的 S. leriifolia 地上部分精油的化学成分和抗菌活性。精油是通过使用 Clevenger 型设备通过水蒸馏法获得的。已使用 GC/FID 和 GC/MS 方法分析了油的化学成分。Kalateh-ye Hizomi 的油产量最高（0.74%），Torbat-e Heydarieh 样品的油产量最低（0.17%）。油中表征的主要化合物是 shyobunol (1.8-22.4 %)、1,8-桉树脑 (6.2-14.1 %)、β-蒎烯 (5.3-13.1 %) 和 α-蒎烯 (1.0-5.1 %)。
