     The essential oil of Peucedanum ru t h e n i c u m fruits, obtained by hydrodistillation, was analyzed by gas chromatography and gas chromatography mass spectrometry. Among the 31 identified constituents accounting for 83.9% of the total oil, the major components were 1,8-cineole (11.15%), camphor (5.86%), Z-carveol (6.88%), l-carvone (5.61%), 8,9-dehydroisolongifolene (1...

Introduction: The aim of this study was to characterize the chemical composition and antimicrobial activity of Trachyspermum copticum essential oil (EO). Methods: The chemical composition of seed samples obtained from Mianeh city in East Azerbaijan, was assessed using gas chromatography-mass spectrometry (GC-MS). The antimicrobial activity was evaluated by disc diffusion method against methicil...

The composition of the essential oil obtained from the dried flowering aerial parts of Artemisia annua L. (Compositae) was analysed by GC and GC/MS. Thirty-two components were identified in the essential oil of A. annua L. with campher (48.00%), 1,8-cineole (9.39%), camphene (6.98%) and spathulenol (4.89%) as major components. The essential oil was evaluated for antibacterial and antifungal act...

      The essential oil of Prangos ferulacea (Apiaceae) fruits was obtained by hydrodistillation and analyzed by gas chromatography (GC) and GC-mass spectrometery (MS). Among the 39 identified constituents accounting for 99.99% of the total oil, the major components were chrysanthenyl acetate (26.53%), limonene (19.59%), alpha pinene (19.50%), delta-3-carene (6.56%), mesitaldehyde (6.0...

This study was carried out to evaluate the antimicrobial and antioxidant activities of different extracts from aerial parts of six Salvia species including Salvia ceratophylla, Salvia chorassanica, Salvia leriifolia, Salvia macrosiphon, Salvia chloroleuca and Salvia virgata. The effect of the extracts against 3 Gram positive and 3 Gram negative bacteria was tested by the micro dilution method. ...
