Chemical Composition and Antibacterial Activity of the Essential Oil from Aerial Parts of Torilis Leptophylla and Thecocarpus Meifolius Two Umbelliferae %K Torilis leptophylla %K Thecocarpus meifolius %K essential oil %K Spathulenol %K Antibacterial activity %R %X In this research, the essential oil of the aerial parts of Torilis leptophylla, collected from Ilam- Province and the essential oil of the aerial parts of Thecocarpus meifolius, collected from Shahre Kord were obtained by microwave and analysed by GC/MS. Spathulenol (15.74%), trans-α-bergamothene (9.37%) and germacrene D (8.94%) were  the major constituents in the oil of T. leptophylla. Spathulenol (30.8%), caryophyllene oxide (8.9%) and germacene D (6.0%) were   the major in the oil of T. meifolius. Antibacterial activity of both oils against gram-positive and gram-negative bacteria were investigated. Both oils showed weak activity against gram-positive bacteria. %U https://www.nsmsi.ir/article_6989_478c5a7ae69364fc7d2e13c7a63c5343.pdf
